Variable visibility across threads

[tnarol]

Hi,

Here's one more of my many multithreading beginner questions (sorry for almost spamming the group !).
I'd like to know the best way to have visibility on a variable from different threads. My current solution is having the variable global in the main thread (which creates the others) and give visibility to other threads by including the .h file were it is declared extern.

Thanks

Or pass the required information as a structure whose pointer is the thread argument. This would allow you to change information in a single file(where structure is defined) if you need to add more information.
