syntax for thread that returns a value

[rick7423]

Ok, I need to create a thread function uses the comm port that is passed a single parameter (char[16]), and it is to return a char * (LPSTR) value.

I already have the comm port functionality completed and this works fine as a single threaded app. I need to port it to a multi-threaded app.

I looked at all of the documentation that I can find, but cannot get a grip on how to get a value back from the thread function.

CreateThread() is passed the function name and params (a struct of type LPVOID, another problem area), but the return value from the CreateThread is the thread ID. How can:
1. Pass the char[16] param to the thread
2. get the LPSTR value returned from the thread comm function.
3. This value MUST be returned prior to procedding with further processing. I am contemplating the use of WaitForSingleObject(...) but am unsure of the downside of it.

An example would be tremendously helpful.

Thanks in advance...
