+  ERROR INJECT MODULE:
+  --------------------
+  These macros are used to insert macros from the application code.
+  The event that activates those error injections can be activated
+  from SQL by using:
+  SET SESSION dbug=+d,code;
+
+  After the error has been injected, the macros will automatically
+  remove the debug code, thus similar to using:
+  SET SESSION dbug=-d,code
+  from SQL.
+
+  ERROR_INJECT_CRASH will inject a crash of the MySQL Server if code
+  is set when macro is called. ERROR_INJECT_CRASH can be used in
+  if-statements, it will always return FALSE unless of course it
+  crashes in which case it doesn't return at all.
+
+  ERROR_INJECT_ACTION will inject the action specified in the action
+  parameter of the macro, before performing the action the code will
+  be removed such that no more events occur. ERROR_INJECT_ACTION
+  can also be used in if-statements and always returns FALSE.
+  ERROR_INJECT can be used in a normal if-statement, where the action
+  part is performed in the if-block. The macro returns TRUE if the
+  error was activated and otherwise returns FALSE. If activated the
+  code is removed.
+
+  Sometimes it is necessary to perform error inject actions as a serie
+  of events. In this case one can use one variable on the THD object.
+  Thus one sets this value by using e.g. SET_ERROR_INJECT_VALUE(100).
+  Then one can later test for it by using ERROR_INJECT_CRASH_VALUE,
+  ERROR_INJECT_ACTION_VALUE and ERROR_INJECT_VALUE. This have the same
+  behaviour as the above described macros except that they use the
+  error inject value instead of a code used by DBUG macros.
