How can I create a thread and, lets say display a simple message in a win32 enviroment, the call 2 funcitons at once?

I am kind of the slow type and msdn confuses me...

HANDLE CreateThread(
LPSECURITY_ATTRIBUTES lpThreadAttributes,
SIZE_T dwStackSize,
LPTHREAD_START_ROUTINE lpStartAddress,
LPVOID lpParameter,
DWORD dwCreationFlags,
LPDWORD lpThreadId
);


Looking at create thread, I see that you can pass values thru LPVOID lpParameter, how can I pass more than one value using create thread?

Also the following code would create two threads that would run at the same time, and so I could run 3 functions at one time?(The two process I created, along with the one that starts when the program is executed)?

hThread = CreateThread(
NULL,
0,
ThreadFunc,
&dwThrdParam,
0,
&dwThreadId);

hThread2 = CreateThread(
NULL,
0,
ThreadFunc2,
&dwThrdParam,
0,
&dwThreadId);

Pass a pointer to a structure, and populate that structure with all your input and output values. The calling thread fills-in the inputs, the worker thread fills-in the outputs.

Yep.

Pack them up in a struct and pass a pointer to that struct to CreateThread[Ex].

Basically, but beware of race conditions and deadlocks. You''re passing the same data to both CreateThread calls. You need to somehow synchronize access to the variable memory; see mutexes, semaphores and critical blocks.
