ASM Community

Hi,

I write a program in VC++ which calls a function written in assembly. The function gets four integer parameters, namely wHour, wMinute, wSecond, and wMilliseconds and returns time in milliseconds. Its works perfectly. Now I'm trying to get the local time within my assembly function
INVOKE GetLocalTime, ADDR sysTime
and have no errors during assembling but when I build my programe in VC++ I get the error: func.obj : error LNK2001: unresolved external symbol _GetLocalTime

What do I wrong?
Thanks.

oleg,

Just as Eternal Idol Birmingham said, GetLocalTime is a stdcall function. For more information, have a look at:

Done, I've fixed it but with windows.inc and not that Irvine2.inc that I don't have. I've tested it and it works.

The problem is the parameter convention, you have declared C in the asm source code which is fine to link to the main.cpp but I will not link to the API. So I've changed that to stdcall and replaced your old C calling of mytime to a stdcall one and now it works.

func.asm:

.model flat,stdcall
include windows.inc

main.cpp:

extern "C" int __stdcall mytime(int,int,int,int);

I've attached the new files anyway :)

Yes, of course because there isn't any real address in the stack, anyway that isn't a code of my own, its your very first code ;)

It was working fine on my machine so I didn't see the rest of the code.
