NAME

       pthread_rwlockattr_destroy - Destroys a previously initialized read-write lock attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_rwlockattr_destroy(
			     pthread_rwlockattr_t	  *attr);

PARAMETERS

       Address of the read-write lock attributes object to be destroyed.

DESCRIPTION

       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.

RETURN VALUES

       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.

ERRORS

       None

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

STANDARDS

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