NAME

       pthread_rwlockattr_init - Initialize a read-write lock attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_rwlockattr_init(
			     pthread_rwlockattr_t	  *attr);

PARAMETERS

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

DESCRIPTION

       This routine initializes the read-write lock attributes object referenced by attr and sets its attributes with default values.

       The results of calling this routine are undefined if attr references an already initialized read-write lock attributes object.

       After  an  initialized  read-write lock attributes object has been used to initialize one or more read-write lock objects, any operation on
       that attributes object (including destruction) has no effect on those read-write lock objects.

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.  Insufficient memory exists to initialize the read-write lock attributes object.

ERRORS

       None
