Title: 64 bit calling convention
Post by: lesliedellow on October 27, 2011, 07:19:56 PM

Unless my memory deceives me, the 64 bit version of Pelles C used to pass arguments in the ecx and sdx registers, but typing pocc /?, in the version I downloaded just now, seems to suggest that __cdecl is the standard calling convention. Has it changed I wonder, or is my memory failing me?

cdecl is the standard for 32 bit Console programs.

32 bit winAPI uses stdcall

64 bit is fastcall
