Hey Hutch--,
Just wondering if on the next release of MASM32 you could update the OPTION PROLOGUE help topic, since it is unclear on three major points:
1. The prologue macro must end with EXITM (I know it is already referred to as a 'macro function', but it could be clearer)
2. The epilogue macro must not end with EXITM (same as above)
3. The value returned by the prologue macro must be the number of bytes of stack space it has used (ref: http://msdn2.microsoft.com/en-US/library/4k8fb3yk.aspx)
It also might be worth putting somewhere (I couldn't find it) that only STDCALL and C calling conventions are supported with the FLAT memory model (ref: http://msdn2.microsoft.com/en-us/library/4zc781yh.aspx)
Cheers,
Zooba :U
Strange, I used SYSCALL here (http://www.masm32.com/board/index.php?topic=3894.0) without problems, and I seem to recall Vortex using it in more than one project.
