cdecl is a Windows 32-bit function calling convention which is very similar to the calling convention used on many POSIX operating systems (documented in the i386 System V ABI). One of the differences is in returning small structs. Parameters Parameters are passed on the stack, with the first arg...

stdcall is used for 32-bit Windows API calls. Parameters Parameters are passed on the stack, with the first parameter closest to the top of the stack. The callee will pop these values off of the stack before returning. Return Value Scalar return values are placed in EAX. Saved and Clobbered Re...
