the value referenced by pshared. The
pshared argument may be one of two values:
PTHREAD_PROCESS_SHARED

() function will return
zero. Otherwise an error number will be returned to indicate the error.
The pthread_rwlockattr_setpshared
()
function will fail if:
EINVAL
]pthread_rwlock_init(3), pthread_rwlockattr_getpshared(3), pthread_rwlockattr_init(3)
The pthread_rwlockattr_setpshared

not supported.
