 * Test that pthread_condattr_getpshared()
 *
 *  It shall obtain the value of the process-shared attribute from 'attr'.
 *
 * Steps:
 * 1.  In a loop, initialize a pthread_condattr_t object with pthread_condattr_init()
 * 2.  Set 'pshared' of the object to PTHREAD_PROCESS_PRIVATE.
 * 3.  Call pthread_condattr_getpshared() to check if the process-shared
 *     attribute is set as PTHREAD_PROCESS_PRIVATE.
