## Detailed Description

Initialize a Mutex.

## Function Documentation

## ◆ pthread_mutex_init()

int pthread_mutex_init | ( | pthread_mutex_t * | mutex,
|  | const pthread_mutexattr_t * | attr
| ) |  |

NOTE: XXX Could be optimized so all the attribute error checking is not performed when attr is NULL.
