stdcall (32-bit)

The stdcall calling convention is almost identical to cdecl in that parameters are passed on to the stack in the same manner--the rightmost is pushed first and leftmost is pushed last. The only difference is that the caller does not have to take care of stack cleanup:

macro stdcall procName, [args]{   if ~args eq      reverse       push args   end if   common   call procName}

Let's consider a simple example that uses both the calling conventions:

cdecl_proc:   push ebp   mov  ebp, esp   ; body of the procedure   mov  esp, ebp   pop  ebp,   retstdcall_proc:   push ebp   mov  ebp, esp   ; body of the procedure   mov  esp, ebp   pop  ebp   ret  8                  ; Increments the stack pointer by 8 bytes after                           ; return, thus releasing the space occupied                            ; by procedure parametersmain: ccall ...
