Detailed Description

Mutex.

Mutexes allow process and threads to access shared resources one at a time. What happens when 2 threads try to access a global variable at the same time!? A mutex is like a thread-safe boolean... not really. When a thread wants to access a shared resource, it will lock a mutex, then when it's done with the resource it will unlock the mutex. If a thread tries to lock an already locked mutex, then it will block until it becomes unlocked.
