Detailed Description

A C++ wrapper for a POSIX mutex attributes.

These are customizations for Mutexes, and are only needed if you want more than the default error checking, if you want recursive behaviour where a thread can hold more than lock on the same mutex, if you are using fine-grained thread scheduling priority, or want to share a Mutex between processes.

See man pages for pthread_mutexattr_init, pthread_mutexattr_settype, pthread_mutexattr_setprioceiling, pthread_mutexattr_setprotocol, and pthread_mutexattr_setpshared.
