PTHREAD_RWLOCKATTR(3)					   BSD Library Functions Manual 				     PTHREAD_RWLOCKATTR(3)

NAME

     pthread_rwlockattr_init, pthread_rwlockattr_destroy -- initialize or destroy read/write lock attributes

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

     #include <pthread.h>

     int
     pthread_rwlockattr_init(pthread_rwlockattr_t *attr);

     int
     pthread_rwlockattr_destroy(pthread_rwlockattr_t *attr);

DESCRIPTION

     The pthread_rwlockattr_init() function is used to initialize a read/write lock attributes object.

     The pthread_rwlockattr_destroy() function is used to destroy a read/write lock attribute object previously created with
     pthread_rwlockattr_init().

RETURN VALUES

     If successful, the pthread_rwlockattr_init() and pthread_rwlockattr_destroy() functions return zero.  Otherwise an error number will be
     returned to indicate the error.

ERRORS

     pthread_rwlockattr_init() shall fail if:

     [ENOMEM]		Insufficient memory exists to initialize the read/write lock attributes object.

     pthread_rwlockattr_init() and pthread_rwlockattr_destroy() may fail if:

     [EINVAL]		The value specified by attr is invalid.

SEE ALSO

     pthread_rwlock_init(3)

STANDARDS

     Both functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
