CreateThread in Windows

[sevak316]

This must be an easy question.

I am trying to create a thread in windows. I am using C as my language.

I am trying to pass a function to the CreateThread function to create a thread. My function has a return type void and paratmeter is void as well. How do I approach this?

Is it something like this?

static void run() {
myThread = CreateThread(
NULL,
0,
MyFunction,
NULL,
0,
NULL);
}

How do I pass my function to CreateThread?

What is this DWORD WINAPI functionName () that I am reading about? Do I need this function?

Thanks in advance,
Sevak.

The function you pass to CreateThread must return a DWORD and be defined with the WINAPI keyword. For example,

DWORD WINAPI run(void* arg); //LPVOID would be more "Windows", not that I really care

sorry, but im confused. I have been lookin at code ALL day!

who ends up calling my funtion and how??
lets say my function is "void xTaskFast(void)"

Then you call CreateThread as follows:

DWORD tid;
HANDLE h = CreateThread(NULL, 0, xFastTask, 0, &tid); //check h to see if it succeeded or not

The spawned thread, if the call is successful, will be created and will start execution at the beginning of the function passed in the third parameter. The thread that called CreateThread will continue from the next line (this should be error checking).
