|  * mutex1e.c

|  *
 | |
|  * As for mutex1.c but with type set to PTHREAD_MUTEX_ERRORCHECK.
 | |
|  *
 | |
|  * Create a simple mutex object, lock it, unlock it, then destroy it.
 | |
|  * This is the simplest test of the pthread mutex family that we can do.
 | |
|  *
 | |
|  * Depends on API functions:
 | |
|  *	pthread_mutexattr_settype()
 | |
|  * 	pthread_mutex_init()
 | |
|  *	pthread_mutex_destroy()
