/GH (Enable _pexit Hook Function)


This option calls the _pexit function at the end of every method or function. The _pexit function is not part of any library and it is up to you to provide a definition for _pexit.

Unless you plan to explicitly call _pexit, you do not need to provide a prototype. The function must appear as if it had the following prototype, and it must push the content of all registers on entry and pop the unchanged content on exit:

void __declspec(naked) _cdecl _pexit( void );

_pexit is similar to _penter; see /Gh for an example of how to write a _pexit function.
