Typedef Documentation

_Unwind_Exception_Cleanup_Fn

typedef void(* _Unwind_Exception_Cleanup_Fn) (_Unwind_Reason_Code reason, _Unwind_Exception *exc)

_Unwind_Exception_Cleanup_Fn

This function is used delete the _Unwind_Exception. Basically, the _Unwind_Exception structure is made up of two parts, the level I part, and the level II part. Since the structure can be larger than what is defined by this spec (i.e. could contain a level II part), the language needs to provide the deleter. The following defines the acceptable reasons:

• _URC_FOREIGN_EXCEPTION_CAUGHT: This indicates that a different runtime caught this exception. Nested foreign exceptions, or rethrowing a foreign exception, result in undefined behavior
• _URC_FATAL_PHASE1_ERROR: The personality routine encountered an error during phase 1
• _URC_FATAL_PHASE2_ERROR: The personality routine encountered an error during phase 2

Parameters

reason	the reason for deleting exc
exc	the _Unwind_Exception to delete

Enumeration Type Documentation

_Unwind_Reason_Code

enum _Unwind_Reason_Code

_Unwind_Reason_Code

The "reason code" is an enum that is used by the following functions:

• _Unwind_Exception_Cleanup_Fn
• _Unwind_RaiseException
• _Unwind_Stop_Fn
• _Unwind_ForcedUnwind
• __personality_routine

It is used to both signal that an error has occurred, as well as tell callback functions what to do, so view it as nothing more than a global enum, were each value has it's own meaning.
