Question

This is my first time dealing with windows. I tried to create thread, but I can’t compile my code.

This is a part of my code:

WORD _tid;
HANDLE  readerThread= CreateThread(0,0,readFromPort,0,0,&_tid); 
DWORD WINAPI readFromPort(LPVOID lpParam ){}

I also tried :

LPDWORD_tid;
HANDLE  readerThread= CreateThread(0,0,readFromPort,0,0,_tid); 
DWORD WINAPI readFromPort(LPVOID lpParam ){}

Neither compiled. onyone knows what is the problem?

(I’m using windows xp)

thanks.

Answer 1

well, don’t know what’s error you have. But can provide a good example to you

#include "windows.h"
DWORD WINAPI readFromPort(LPVOID lpParam ){return 0;}
int _tmain(int argc, _TCHAR* argv[])
{
    DWORD _tid;
    HANDLE  readerThread= CreateThread(0,0,readFromPort,0,0,&_tid); 
    return 0;
}

difference to yours:

1. _tid is DWORD, not WORD.

2. the readFromPort returns value 0.
