pthread_rwlockattr_init(3)
NAME
  pthread_rwlockattr_init - Initialize a read-write lock attributes object

SYNOPSIS
  #include <pthread.h>

  int pthread_rwlockattr_init(
	  pthread_rwlockattr_t *attr );

LIBRARY
  DECthreads POSIX 1003.1c Library (libpthread.so)

PARAMETERS
  attr
      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:

  0   Successful completion.

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

ERRORS
  None
