Significance of 'return (int) msg.wParam'?

Hello. I am new to multithreading and was on my way through a simple tutorial when I ran across this line to end the primary thread.

return (int) msg.wParam;

I am used to ending my programs in 'return(0);' and was curious as to what the significance of this statement is? Is this the way a thread (using windows API) checks for a success or failure on program termination? Or is there some other reason for this statement?

Thank you in advance for the help!

A thread can return anything it wishes when it exits - it's up to the programmer to decide what to return.

You use ExitCodeThread to retrieve the value.

Lastly, the OS doesn't care what value is returned.

Thanks for the help, that cleared things up for me.
