DECthreads POSIX 1003.1c Library (libpthread.so)
Address of the read-write lock attributes object to be destroyed.
This routine destroys the read-write lock attributes object referenced by attr -- that is, the object becomes uninitialized.
After successful completion of this routine, the results of using attr in a call to any routine (other than pthread_rwlockattr_init) are unpredictable.
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The value specified by attr is invalid.
Functions: pthread_rwlockattr_init(3), pthread_rwlock_init(3)
