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
