NAME    [Toc]    [Back]

     pthread_rwlockattr_init, pthread_rwlockattr_destroy - initialize/destroy
     a read-write lock attribute object

C SYNOPSIS    [Toc]    [Back]

     #include <pthread.h>

     int pthread_rwlockattr_init(pthread_rwlockattr_t *attr);
     int pthread_rwlockattr_destroy(pthread_rwlockattr_t *attr);

DESCRIPTION    [Toc]    [Back]

     The function pthread_rwlockattr_init() initializes	the read-write lock
     attribute object referenced by attr to the	default	attribute values.  The
     default sharing value is PTHREAD_PROCESS_PRIVATE.

     Once a read-write lock attribute object is	used to	initialize one or more
     read-write	locks, any function that affects the attribute object will not
     affect the	previously initialized read-write locks.
     pthread_rwlockattr_destroy() uninitializes	the read-write lock attribute
     structure referenced by attr.

DIAGNOSTICS    [Toc]    [Back]

     These functions return zero.
