#
# These are the Cython pxd files for (most of) the Python/C API.
#
# REFERENCE COUNTING:
#
# JUST TO SCARE YOU:
# If you are going to use any of the Python/C API in your Cython
# program, you might be responsible for doing reference counting.
# Read http://docs.python.org/api/refcounts.html which is so
# important I've copied it below.
#
# For all the declaration below, whenver the Py_ function returns
# a *new reference* to a PyObject*, the return type is "object".
# When the function returns a borrowed reference, the return
# type is PyObject*. When Cython sees "object" as a return type
# it doesn't increment the reference count. When it sees PyObject*
# in order to use the result you must explicitly cast to <object>,
# and when you do that Cython increments the reference count wether
# you want it to or not, forcing you to an explicit DECREF (or leak memory).
# To avoid this we make the above convention. Note, you can
# always locally override this convention by putting something like
#
# cdef extern from "Python.h":
# PyObject* PyNumber_Add(PyObject *o1, PyObject *o2)
#
# in your file after any .pxi includes. Cython will use the latest
# declaration.
#
# Cython takes care of this automatically for anything of type object.
## More precisely, I think the correct convention for
## using the Python/C API from Pyrex is as follows.
##
## (1) Declare all input arguments as type "object". This way no explicit
## <PyObject*> casting is needed, and moreover Pyrex doesn't generate
## any funny reference counting.
## (2) Declare output as object if a new reference is returned.
## (3) Declare output as PyObject* if a borrowed reference is returned.
##
## This way when you call objects, no cast is needed, and if the api
## calls returns a new reference (which is about 95% of them), then
## you can just assign to a variable of type object. With borrowed
## references if you do an explicit typecast to <object>, Pyrex generates an
## INCREF and DECREF so you have to be careful. However, you got a
## borrowed reference in this case, so there's got to be another reference
## to your object, so you're OK, as long as you relealize this
## and use the result of an explicit cast to <object> as a borrowed
## reference (and you can call Py_INCREF if you want to turn it
## into another reference for some reason).
#
# "The reference count is important because today's computers have
# a finite (and often severely limited) memory size; it counts how
# many different places there are that have a reference to an
# object. Such a place could be another object, or a global (or
# static) C variable, or a local variable in some C function. When
# an object's reference count becomes zero, the object is
# deallocated. If it contains references to other objects, their
# reference count is decremented. Those other objects may be
# deallocated in turn, if this decrement makes their reference
# count become zero, and so on. (There's an obvious problem with
# objects that reference each other here; for now, the solution is
# ``don't do that.'')
#
# Reference counts are always manipulated explicitly. The normal
# way is to use the macro Py_INCREF() to increment an object's
# reference count by one, and Py_DECREF() to decrement it by
# one. The Py_DECREF() macro is considerably more complex than the
# incref one, since it must check whether the reference count
# becomes zero and then cause the object's deallocator to be
# called. The deallocator is a function pointer contained in the
# object's type structure. The type-specific deallocator takes
# care of decrementing the reference counts for other objects
# contained in the object if this is a compound object type, such
# as a list, as well as performing any additional finalization
# that's needed. There's no chance that the reference count can
# overflow; at least as many bits are used to hold the reference
# count as there are distinct memory locations in virtual memory
# (assuming sizeof(long) >= sizeof(char*)). Thus, the reference
# count increment is a simple operation.
#
# It is not necessary to increment an object's reference count for
# every local variable that contains a pointer to an object. In
# theory, the object's reference count goes up by one when the
# variable is made to point to it and it goes down by one when the
# variable goes out of scope. However, these two cancel each other
# out, so at the end the reference count hasn't changed. The only
# real reason to use the reference count is to prevent the object
# from being deallocated as long as our variable is pointing to
# it. If we know that there is at least one other reference to the
# object that lives at least as long as our variable, there is no
# need to increment the reference count temporarily. An important
# situation where this arises is in objects that are passed as
# arguments to C functions in an extension module that are called
# from Python; the call mechanism guarantees to hold a reference
# to every argument for the duration of the call.
#
# However, a common pitfall is to extract an object from a list
# and hold on to it for a while without incrementing its reference
# count. Some other operation might conceivably remove the object
# from the list, decrementing its reference count and possible
# deallocating it. The real danger is that innocent-looking
# operations may invoke arbitrary Python code which could do this;
# there is a code path which allows control to flow back to the
# user from a Py_DECREF(), so almost any operation is potentially
# dangerous.
#
# A safe approach is to always use the generic operations
# (functions whose name begins with "PyObject_", "PyNumber_",
# "PySequence_" or "PyMapping_"). These operations always
# increment the reference count of the object they return. This
# leaves the caller with the responsibility to call Py_DECREF()
# when they are done with the result; this soon becomes second
# nature.
#
# Now you should read http://docs.python.org/api/refcountDetails.html
# just to be sure you understand what is going on.

# Intern the argument *string in place. The argument must be the

# 7.4.1 Dictionary Objects
############################################################################
# PyDictObject
#
# This subtype of PyObject represents a Python dictionary object
# (i.e. the 'dict' type).
# PyTypeObject PyDict_Type
#
# This instance of PyTypeObject represents the Python dictionary
# type. This is exposed to Python programs as dict and
# types.DictType.
bint PyDict_Check(object p)
# Return true if p is a dict object or an instance of a subtype of
# the dict type.
bint PyDict_CheckExact(object p)
# Return true if p is a dict object, but not an instance of a
# subtype of the dict type.
object PyDict_New()
# Return value: New reference.
# Return a new empty dictionary, or NULL on failure.
object PyDictProxy_New(object dict)
# Return value: New reference.
# Return a proxy object for a mapping which enforces read-only
# behavior. This is normally used to create a proxy to prevent
# modification of the dictionary for non-dynamic class types.
void PyDict_Clear(object p)
# Empty an existing dictionary of all key-value pairs.
int PyDict_Contains(object p, object key) except -1
# Determine if dictionary p contains key. If an item in p is
# matches key, return 1, otherwise return 0. On error, return
# -1. This is equivalent to the Python expression "key in p".
object PyDict_Copy(object p)
# Return value: New reference.
# Return a new dictionary that contains the same key-value pairs as p.
int PyDict_SetItem(object p, object key, object val) except -1
# Insert value into the dictionary p with a key of key. key must
# be hashable; if it isn't, TypeError will be raised. Return 0 on
# success or -1 on failure.
int PyDict_SetItemString(object p, char *key, object val) except -1
# Insert value into the dictionary p using key as a key. key
# should be a char*. The key object is created using
# PyString_FromString(key). Return 0 on success or -1 on failure.
int PyDict_DelItem(object p, object key) except -1
# Remove the entry in dictionary p with key key. key must be
# hashable; if it isn't, TypeError is raised. Return 0 on success
# or -1 on failure.
int PyDict_DelItemString(object p, char *key) except -1
# Remove the entry in dictionary p which has a key specified by
# the string key. Return 0 on success or -1 on failure.
PyObject* PyDict_GetItem(object p, object key)
# Return value: Borrowed reference.
# Return the object from dictionary p which has a key key. Return
# NULL if the key key is not present, but without setting an
# exception.
PyObject* PyDict_GetItemString(object p, char *key)
# Return value: Borrowed reference.
# This is the same as PyDict_GetItem(), but key is specified as a
# char*, rather than a PyObject*.
object PyDict_Items(object p)
# Return value: New reference.
# Return a PyListObject containing all the items from the
# dictionary, as in the dictionary method items() (see the Python
# Library Reference).
object PyDict_Keys(object p)
# Return value: New reference.
# Return a PyListObject containing all the keys from the
# dictionary, as in the dictionary method keys() (see the Python
# Library Reference).
object PyDict_Values(object p)
# Return value: New reference.
# Return a PyListObject containing all the values from the
# dictionary p, as in the dictionary method values() (see the
# Python Library Reference).
Py_ssize_t PyDict_Size(object p) except -1
# Return the number of items in the dictionary. This is equivalent
# to "len(p)" on a dictionary.
int PyDict_Next(object p, Py_ssize_t *ppos, PyObject* *pkey, PyObject* *pvalue)
# Iterate over all key-value pairs in the dictionary p. The int
# referred to by ppos must be initialized to 0 prior to the first
# call to this function to start the iteration; the function
# returns true for each pair in the dictionary, and false once all
# pairs have been reported. The parameters pkey and pvalue should
# either point to PyObject* variables that will be filled in with
# each key and value, respectively, or may be NULL. Any references
# returned through them are borrowed. ppos should not be altered
# during iteration. Its value represents offsets within the
# internal dictionary structure, and since the structure is
# sparse, the offsets are not consecutive.
# For example:
#
#object key, *value;
#int pos = 0;
#
#while (PyDict_Next(self->dict, &pos, &key, &value)) {
# /* do something interesting with the values... */
# ...
#}
# The dictionary p should not be mutated during iteration. It is
# safe (since Python 2.1) to modify the values of the keys as you
# iterate over the dictionary, but only so long as the set of keys
# does not change. For example:
# object key, *value;
# int pos = 0;
# while (PyDict_Next(self->dict, &pos, &key, &value)) {
# int i = PyInt_AS_LONG(value) + 1;
# object o = PyInt_FromLong(i);
# if (o == NULL)
# return -1;
# if (PyDict_SetItem(self->dict, key, o) < 0) {
# Py_DECREF(o);
# return -1;
# }
# Py_DECREF(o);
# }
int PyDict_Merge(object a, object b, int override) except -1
# Iterate over mapping object b adding key-value pairs to
# dictionary a. b may be a dictionary, or any object supporting
# PyMapping_Keys() and PyObject_GetItem(). If override is true,
# existing pairs in a will be replaced if a matching key is found
# in b, otherwise pairs will only be added if there is not a
# matching key in a. Return 0 on success or -1 if an exception was
# raised.
int PyDict_Update(object a, object b) except -1
# This is the same as PyDict_Merge(a, b, 1) in C, or a.update(b)
# in Python. Return 0 on success or -1 if an exception was raised.
int PyDict_MergeFromSeq2(object a, object seq2, int override) except -1
# Update or merge into dictionary a, from the key-value pairs in
# seq2. seq2 must be an iterable object producing iterable objects
# of length 2, viewed as key-value pairs. In case of duplicate
# keys, the last wins if override is true, else the first
# wins. Return 0 on success or -1 if an exception was
# raised. Equivalent Python (except for the return value):
#
#def PyDict_MergeFromSeq2(a, seq2, override):
# for key, value in seq2:
# if override or key not in a:
# a[key] = value

# 9.2 Memory Interface
#####################################################################
# You are definitely *supposed* to use these: "In most situations,
# however, it is recommended to allocate memory from the Python
# heap specifically because the latter is under control of the
# Python memory manager. For example, this is required when the
# interpreter is extended with new object types written in
# C. Another reason for using the Python heap is the desire to
# inform the Python memory manager about the memory needs of the
# extension module. Even when the requested memory is used
# exclusively for internal, highly-specific purposes, delegating
# all memory requests to the Python memory manager causes the
# interpreter to have a more accurate image of its memory
# footprint as a whole. Consequently, under certain circumstances,
# the Python memory manager may or may not trigger appropriate
# actions, like garbage collection, memory compaction or other
# preventive procedures. Note that by using the C library
# allocator as shown in the previous example, the allocated memory
# for the I/O buffer escapes completely the Python memory
# manager."
# The following function sets, modeled after the ANSI C standard,
# but specifying behavior when requesting zero bytes, are
# available for allocating and releasing memory from the Python
# heap:
void* PyMem_Malloc(size_t n)
# Allocates n bytes and returns a pointer of type void* to the
# allocated memory, or NULL if the request fails. Requesting zero
# bytes returns a distinct non-NULL pointer if possible, as if
# PyMem_Malloc(1) had been called instead. The memory will not
# have been initialized in any way.
void* PyMem_Realloc(void *p, size_t n)
# Resizes the memory block pointed to by p to n bytes. The
# contents will be unchanged to the minimum of the old and the new
# sizes. If p is NULL, the call is equivalent to PyMem_Malloc(n);
# else if n is equal to zero, the memory block is resized but is
# not freed, and the returned pointer is non-NULL. Unless p is
# NULL, it must have been returned by a previous call to
# PyMem_Malloc() or PyMem_Realloc().
void PyMem_Free(void *p)
# Frees the memory block pointed to by p, which must have been
# returned by a previous call to PyMem_Malloc() or
# PyMem_Realloc(). Otherwise, or if PyMem_Free(p) has been called
# before, undefined behavior occurs. If p is NULL, no operation is
# performed.
# The following type-oriented macros are provided for
# convenience. Note that TYPE refers to any C type.
# TYPE* PyMem_New(TYPE, size_t n)
# Same as PyMem_Malloc(), but allocates (n * sizeof(TYPE)) bytes
# of memory. Returns a pointer cast to TYPE*. The memory will not
# have been initialized in any way.
# TYPE* PyMem_Resize(void *p, TYPE, size_t n)
# Same as PyMem_Realloc(), but the memory block is resized to (n *
# sizeof(TYPE)) bytes. Returns a pointer cast to TYPE*.
void PyMem_Del(void *p)
# Same as PyMem_Free().
# In addition, the following macro sets are provided for calling
# the Python memory allocator directly, without involving the C
# API functions listed above. However, note that their use does
# not preserve binary compatibility across Python versions and is
# therefore deprecated in extension modules.
# PyMem_MALLOC(), PyMem_REALLOC(), PyMem_FREE().
# PyMem_NEW(), PyMem_RESIZE(), PyMem_DEL().

# Return value: New reference.
# This is a simplified interface to PyImport_ImportModuleEx()
# below, leaving the globals and locals arguments set to
# NULL. When the name argument contains a dot (when it specifies a
# submodule of a package), the fromlist argument is set to the
# list ['*'] so that the return value is the named module rather
# than the top-level package containing it as would otherwise be
# the case. (Unfortunately, this has an additional side effect
# when name in fact specifies a subpackage instead of a submodule:
# the submodules specified in the package's __all__ variable are
# loaded.) Return a new reference to the imported module, or NULL
# with an exception set on failure.
object PyImport_ImportModuleEx(char *name, object globals, object locals, object fromlist)
# Return value: New reference.
# Import a module. This is best described by referring to the
# built-in Python function __import__(), as the standard
# __import__() function calls this function directly.
# The return value is a new reference to the imported module or
# top-level package, or NULL with an exception set on failure
# (before Python 2.4, the module may still be created in this
# case). Like for __import__(), the return value when a submodule
# of a package was requested is normally the top-level package,
# unless a non-empty fromlist was given. Changed in version 2.4:
# failing imports remove incomplete module objects.
object PyImport_Import(object name)
# Return value: New reference.
# This is a higher-level interface that calls the current ``import
# hook function''. It invokes the __import__() function from the
# __builtins__ of the current globals. This means that the import
# is done using whatever import hooks are installed in the current
# environment, e.g. by rexec or ihooks.
object PyImport_ReloadModule(object m)
# Return value: New reference.
# Reload a module. This is best described by referring to the
# built-in Python function reload(), as the standard reload()
# function calls this function directly. Return a new reference to
# the reloaded module, or NULL with an exception set on failure
# (the module still exists in this case).
PyObject* PyImport_AddModule(char *name) except NULL
# Return value: Borrowed reference.
# Return the module object corresponding to a module name. The
# name argument may be of the form package.module. First check the
# modules dictionary if there's one there, and if not, create a
# new one and insert it in the modules dictionary. Return NULL
# with an exception set on failure. Note: This function does not
# load or import the module; if the module wasn't already loaded,
# you will get an empty module object. Use PyImport_ImportModule()
# or one of its variants to import a module. Package structures
# implied by a dotted name for name are not created if not already
# present.
object PyImport_ExecCodeModule(char *name, object co)
# Return value: New reference.
# Given a module name (possibly of the form package.module) and a
# code object read from a Python bytecode file or obtained from
# the built-in function compile(), load the module. Return a new
# reference to the module object, or NULL with an exception set if
# an error occurred. Name is removed from sys.modules in error
# cases, and even if name was already in sys.modules on entry to
# PyImport_ExecCodeModule(). Leaving incompletely initialized
# modules in sys.modules is dangerous, as imports of such modules
# have no way to know that the module object is an unknown (and
# probably damaged with respect to the module author's intents)
# state.
# This function will reload the module if it was already
# imported. See PyImport_ReloadModule() for the intended way to
# reload a module.
# If name points to a dotted name of the form package.module, any
# package structures not already created will still not be
# created.
long PyImport_GetMagicNumber()
# Return the magic number for Python bytecode files (a.k.a. .pyc
# and .pyo files). The magic number should be present in the first

PyObject* PyImport_GetModuleDict() except NULL
# Return value: Borrowed reference.

# Load a frozen module named name. Return 1 for success, 0 if the

# initialization failed. To access the imported module on a
# successful load, use PyImport_ImportModule(). (Note the misnomer
# -- this function would reload the module if it was already
# imported.)
int PyImport_ExtendInittab(_inittab *newtab) except -1
# Add a collection of modules to the table of built-in
# modules. The newtab array must end with a sentinel entry which
# contains NULL for the name field; failure to provide the

# This section details the public API for set and frozenset
# objects. Any functionality not listed below is best accessed
# using the either the abstract object protocol (including

# PySetObject
# This subtype of PyObject is used to hold the internal data for
# both set and frozenset objects. It is like a PyDictObject in
# that it is a fixed size for small sets (much like tuple storage)
# and will point to a separate, variable sized block of memory for
# medium and large sized sets (much like list storage). None of
# the fields of this structure should be considered public and are
# subject to change. All access should be done through the
# documented API rather than by manipulating the values in the
# structure.
# PyTypeObject PySet_Type
# This is an instance of PyTypeObject representing the Python set type.
# PyTypeObject PyFrozenSet_Type
# This is an instance of PyTypeObject representing the Python frozenset type.
# The following type check macros work on pointers to any Python
# object. Likewise, the constructor functions work with any
# iterable Python object.

##################################################################### # Present for backwards compatability
# from cpython cimport *
# These are the Cython pxd files for (most of) the Python/C API.
#
# REFERENCE COUNTING:
#
# JUST TO SCARE YOU:
# If you are going to use any of the Python/C API in your Cython
# program, you might be responsible for doing reference counting.
# Read http://docs.python.org/api/refcounts.html which is so
# important I've copied it below.
#
# For all the declaration below, whenver the Py_ function returns
# a *new reference* to a PyObject*, the return type is "object".
# When the function returns a borrowed reference, the return
# type is PyObject*. When Cython sees "object" as a return type
# it doesn't increment the reference count. When it sees PyObject*
# in order to use the result you must explicitly cast to <object>,
# and when you do that Cython increments the reference count wether
# you want it to or not, forcing you to an explicit DECREF (or leak memory).
# To avoid this we make the above convention. Note, you can
# always locally override this convention by putting something like
#
# cdef extern from "Python.h":
# PyObject* PyNumber_Add(PyObject *o1, PyObject *o2)
#
# in your file after any .pxi includes. Cython will use the latest
# declaration.
#
# Cython takes care of this automatically for anything of type object.
## More precisely, I think the correct convention for
## using the Python/C API from Pyrex is as follows.
##
## (1) Declare all input arguments as type "object". This way no explicit
## <PyObject*> casting is needed, and moreover Pyrex doesn't generate
## any funny reference counting.
## (2) Declare output as object if a new reference is returned.
## (3) Declare output as PyObject* if a borrowed reference is returned.
##
## This way when you call objects, no cast is needed, and if the api
## calls returns a new reference (which is about 95% of them), then
## you can just assign to a variable of type object. With borrowed
## references if you do an explicit typecast to <object>, Pyrex generates an
## INCREF and DECREF so you have to be careful. However, you got a
## borrowed reference in this case, so there's got to be another reference
## to your object, so you're OK, as long as you relealize this
## and use the result of an explicit cast to <object> as a borrowed
## reference (and you can call Py_INCREF if you want to turn it
## into another reference for some reason).
#
# "The reference count is important because today's computers have
# a finite (and often severely limited) memory size; it counts how
# many different places there are that have a reference to an
# object. Such a place could be another object, or a global (or
# static) C variable, or a local variable in some C function. When
# an object's reference count becomes zero, the object is
# deallocated. If it contains references to other objects, their
# reference count is decremented. Those other objects may be
# deallocated in turn, if this decrement makes their reference
# count become zero, and so on. (There's an obvious problem with
# objects that reference each other here; for now, the solution is
# ``don't do that.'')
#
# Reference counts are always manipulated explicitly. The normal
# way is to use the macro Py_INCREF() to increment an object's
# reference count by one, and Py_DECREF() to decrement it by
# one. The Py_DECREF() macro is considerably more complex than the
# incref one, since it must check whether the reference count
# becomes zero and then cause the object's deallocator to be
# called. The deallocator is a function pointer contained in the
# object's type structure. The type-specific deallocator takes
# care of decrementing the reference counts for other objects
# contained in the object if this is a compound object type, such
# as a list, as well as performing any additional finalization
# that's needed. There's no chance that the reference count can
# overflow; at least as many bits are used to hold the reference
# count as there are distinct memory locations in virtual memory
# (assuming sizeof(long) >= sizeof(char*)). Thus, the reference
# count increment is a simple operation.
#
# It is not necessary to increment an object's reference count for
# every local variable that contains a pointer to an object. In
# theory, the object's reference count goes up by one when the
# variable is made to point to it and it goes down by one when the
# variable goes out of scope. However, these two cancel each other
# out, so at the end the reference count hasn't changed. The only
# real reason to use the reference count is to prevent the object
# from being deallocated as long as our variable is pointing to
# it. If we know that there is at least one other reference to the
# object that lives at least as long as our variable, there is no
# need to increment the reference count temporarily. An important
# situation where this arises is in objects that are passed as
# arguments to C functions in an extension module that are called
# from Python; the call mechanism guarantees to hold a reference
# to every argument for the duration of the call.
#
# However, a common pitfall is to extract an object from a list
# and hold on to it for a while without incrementing its reference
# count. Some other operation might conceivably remove the object
# from the list, decrementing its reference count and possible
# deallocating it. The real danger is that innocent-looking
# operations may invoke arbitrary Python code which could do this;
# there is a code path which allows control to flow back to the
# user from a Py_DECREF(), so almost any operation is potentially
# dangerous.
#
# A safe approach is to always use the generic operations
# (functions whose name begins with "PyObject_", "PyNumber_",
# "PySequence_" or "PyMapping_"). These operations always
# increment the reference count of the object they return. This
# leaves the caller with the responsibility to call Py_DECREF()
# when they are done with the result; this soon becomes second
# nature.
#

# Return true if o is of type PyBool_Type.
#PyObject* Py_False
# The Python False object. This object has no methods. It needs to

# counts.
#PyObject* Py_True
# The Python True object. This object has no methods. It needs to
# be treated just like any other object with respect to reference
# counts.

bint PyBytes_CheckExact(object o)
# Return true if the object o is a string object, but not an instance of a subtype of the string type.

# Return value: New reference.
# Return a new string object with the value v on success, and NULL
# on failure. The parameter v must not be NULL; it will not be
# checked.
object PyBytes_FromStringAndSize(char *v, Py_ssize_t len)
# Return value: New reference.
# Return a new string object with the value v and length len on
# success, and NULL on failure. If v is NULL, the contents of the
# string are uninitialized.
object PyBytes_FromFormat(char *format, ...)
# Return value: New reference.
# Take a C printf()-style format string and a variable number of
# arguments, calculate the size of the resulting Python string and
# return a string with the values formatted into it. The variable
# arguments must be C types and must correspond exactly to the
# format characters in the format string. The following format
# characters are allowed:
# Format Characters Type Comment
# %% n/a The literal % character.
# %c int A single character, represented as an C int.
# %d int Exactly equivalent to printf("%d").
# %u unsigned int Exactly equivalent to printf("%u").
# %ld long Exactly equivalent to printf("%ld").
# %lu unsigned long Exactly equivalent to printf("%lu").
# %zd Py_ssize_t Exactly equivalent to printf("%zd").
# %zu size_t Exactly equivalent to printf("%zu").
# %i int Exactly equivalent to printf("%i").
# %x int Exactly equivalent to printf("%x").

# %p void* The hex representation of a C pointer.
# Mostly equivalent to printf("%p") except that it is guaranteed to
# start with the literal 0x regardless of what the platform's printf
# yields.
# An unrecognized format character causes all the rest of the
# format string to be copied as-is to the result string, and any
# extra arguments discarded.
object PyBytes_FromFormatV(char *format, va_list vargs)
# Return value: New reference.
# Identical to PyBytes_FromFormat() except that it takes exactly two arguments.

Py_ssize_t PyBytes_GET_SIZE(object string)
# Macro form of PyBytes_Size() but without error checking.

# string. The pointer refers to the internal buffer of string, not
# a copy. The data must not be modified in any way, unless the
# string was just created using PyBytes_FromStringAndSize(NULL,

# object, this function computes the default encoding of string
# and operates on that. If string is not a string object at all,
# PyBytes_AsString() returns NULL and raises TypeError.

# Macro form of PyBytes_AsString() but without error
# checking. Only string objects are supported; no Unicode objects
# should be passed.
int PyBytes_AsStringAndSize(object obj, char **buffer, Py_ssize_t *length) except -1
# Return a NULL-terminated representation of the contents of the

void PyBytes_Concat(PyObject **string, object newpart)
# Create a new string object in *string containing the contents of
# newpart appended to string; the caller will own the new
# reference. The reference to the old value of string will be
# stolen. If the new string cannot be created, the old reference
# to string will still be discarded and the value of *string will
# be set to NULL; the appropriate exception will be set.
void PyBytes_ConcatAndDel(PyObject **string, object newpart)
# Create a new string object in *string containing the contents of
# newpart appended to string. This version decrements the
# reference count of newpart.
int _PyBytes_Resize(PyObject **string, Py_ssize_t newsize) except -1
# A way to resize a string object even though it is
# ``immutable''. Only use this to build up a brand new string
# object; don't use this if the string may already be known in
# other parts of the code. It is an error to call this function if
# the refcount on the input string object is not one. Pass the
# address of an existing string object as an lvalue (it may be
# written into), and the new size desired. On success, *string
# holds the resized string object and 0 is returned; the address
# in *string may differ from its input value. If the reallocation
# fails, the original string object at *string is deallocated,
# *string is set to NULL, a memory exception is set, and -1 is
# returned.
object PyBytes_Format(object format, object args)
# Return value: New reference. Return a new string object from
# format and args. Analogous to format % args. The args argument
# must be a tuple.
void PyBytes_InternInPlace(PyObject **string)
# Intern the argument *string in place. The argument must be the
# address of a pointer variable pointing to a Python string
# object. If there is an existing interned string that is the same
# as *string, it sets *string to it (decrementing the reference
# count of the old string object and incrementing the reference
# count of the interned string object), otherwise it leaves
# *string alone and interns it (incrementing its reference
# count). (Clarification: even though there is a lot of talk about
# reference counts, think of this function as
# reference-count-neutral; you own the object after the call if
# and only if you owned it before the call.)
object PyBytes_InternFromString(char *v)
# Return value: New reference.
# A combination of PyBytes_FromString() and
# PyBytes_InternInPlace(), returning either a new string object
# that has been interned, or a new (``owned'') reference to an
# earlier interned string object with the same value.
object PyBytes_Decode(char *s, Py_ssize_t size, char *encoding, char *errors)
# Return value: New reference.
# Create an object by decoding size bytes of the encoded buffer s
# using the codec registered for encoding. encoding and errors
# have the same meaning as the parameters of the same name in the
# unicode() built-in function. The codec to be used is looked up
# using the Python codec registry. Return NULL if an exception was
# raised by the codec.
object PyBytes_AsDecodedObject(object str, char *encoding, char *errors)
# Return value: New reference.
# Decode a string object by passing it to the codec registered for
# encoding and return the result as Python object. encoding and

# raised.
int PyDict_Update(object a, object b) except -1
# This is the same as PyDict_Merge(a, b, 1) in C, or a.update(b)

# Update or merge into dictionary a, from the key-value pairs in
