[thread.mutex.requirements.general] (original) (raw)

A mutex object facilitates protection against data races and allows safe synchronization of data between execution agents.

An execution agent owns a mutex from the time it successfully calls one of the lock functions until it calls unlock.

Mutexes can be either recursive or non-recursive, and can grant simultaneous ownership to one or many execution agents.

Both recursive and non-recursive mutexes are supplied.
