Update.
2000-07-06 Ulrich Drepper <drepper@redhat.com> * condvar.c: Implement pthread_condattr_getpshared and pthread_condattr_setpshared. * mutex.c: Implement pthread_mutexattr_getpshared and pthread_mutexattr_setpshared. * Versions: Export new functions. * sysdeps/pthread/pthread.h: Add prototypes for new functions. * rwlock.c (pthread_rwlockattr_init): Use PTHREAD_PROCESS_PRIVATE. (pthread_rwlockattr_setpshared): Fail if PTHREAD_PROCESS_PRIVATE is not selected.
