6. __cdecl, the C-style calling convention

• For example,

      add3nums PROC NEAR32 C
  

• Here, add3nums is the first line of procedure declaration.

• Calls to add3nums should be made similar to a C function call, that is,

  1. caller pushes parameters into the stack in the reverse order (right-to-left)

  2. calling the function

  3. popping the stack to clean up those pushed arguments.

      ; example of __cdecl
      push arg3
      push arg2
      push arg1
      call function
      add  sp,12 ; effectively pop; pop; pop;
  

• Function return values are returned in the EAX register.
