c++11 - Codeblocks c++ multithreading huge error list

Question

I was playing around with some multithreading example code shown below (taken from from http://www.bogotobogo.com/cplusplus/multithreading_win32A.php) using codeblocks (build option was set to c++11).

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

DWORD WINAPI myThread(LPVOID lpParameter)
{
    unsigned int& myCounter = *((unsigned int*)lpParameter);
    while(myCounter < 0xFFFFFFFF) ++myCounter;
    return 0;
}

int main(int argc, char* argv[])
{
    using namespace std;

    unsigned int myCounter = 0;
    DWORD myThreadID;
    HANDLE myHandle = CreateThread(0, 0, myThread, &myCounter, 0, &myThreadID);
    char myChar = ' ';
    while(myChar != 'q') {
        cout << myCounter << endl;
        myChar = getchar();
    }

    CloseHandle(myHandle);
    return 0;
}

When I built the project the "cwchar" file was opened and I got the huge list of "has not declared" errors shown below. I'm not sure what's wrong here, any ideas?

Answer 1

Please read the error message, you have a typo in your code:

    HANDLE myHandle = CreateThread(0, 0, myThread, &myCounter;, 0, &myThreadID;);

Remove the extra ';' from this line and you should be fine!
