36  * As for mutex1.c but with type set to PTHREAD_MUTEX_RECURSIVE.
37  *
38  * Create a simple mutex object, lock it, unlock it, then destroy it.
39  * This is the simplest test of the pthread mutex family that we can do.
40  *
41  * Depends on API functions:
42  *	pthread_mutexattr_settype()
43  * 	pthread_mutex_init()
44  *	pthread_mutex_destroy()
