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()
