 * Test that pthread_mutexattr_getpshared()
 *
 *  It shall obtain the value of the process-shared attribute from 'attr'.
 *
 * Steps:
 * 1.  Initialize a pthread_mutexattr_t object with pthread_mutexattr_init()
 * 2.  Set 'pshared' of the object to PTHREAD_PROCESS_SHARED.
 * 3.  Call pthread_mutexattr_getpshared() to check if the process-shared
 *     attribute is set as PTHREAD_PROCESS_SHARED.
