Threads evc

Jeg tror følgende ville kunne bruges:

#include <stdio.h>
#include <windows.h>

DWORD WINAPI MyThread(LPVOID lpParam)
{
    int i = 0;
    while (true)
    {
        printf("%i\n");
        i++;

        if (i == 10)
            ExitThread(0);
    }
    return 0;
}

int main(int argc, char* argv[])
{
    DWORD dwThreadId, dwThrdParam = 1;
    HANDLE hThread;

    hThread = CreateThread(NULL, 0, MyThread, &dwThrdParam, 0, &dwThreadId);
               
    if (hThread != NULL)
        CloseHandle(hThread);

    return 0;
}

Det går galt i main funktionen, den kender ikke hThread:(

har løst problemet med dette eksempel


    #include <stdio.h>
    #include <windows.h> // for all the Win32 specific thread information

    DWORD WINAPI MyThread(LPVOID); // Standard function prototype for Win32 thread

    void main(void)
    {
        DWORD iID[1];        // array of thread id's
        HANDLE hThreads[1]; // array of thread handles
        DWORD waiter;        // flag which is set when all therads finish

        // create two threads which do the exact same thing
        hThreads[0] = CreateThread(NULL,0,MyThread,"T1",NULL,&iID[0]);

        // wait until threads have finished before parent thread exits
        waiter = WaitForMultipleObjects(2,hThreads,TRUE,INFINITE);
    } 

    DWORD WINAPI MyThread(LPVOID n)  // defines what our threads actually do
    {
        char* name = (char*)n;  // needed to convert passed parameter to a string
        for (int i=0;i<100; i++)
            printf("Thread %s: i=%d\n",name,i);
        return 0;
    }
