NAME
       pthread_condattr_init, pthread_condattr_destroy - initialize or destroy condition variable attributes object

SYNOPSIS
       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_condattr_init(pthread_condattr_t *attr);

       int pthread_condattr_destroy(pthread_condattr_t *attr);

       The  pthread_condattr_init()  function  initializes  a  condition  variable  attributes	object	attr with the default value for all of the
       attributes defined by the implementation.

       At present, the only attribute available is the scope of condition variables. The default scope of the attribute  is   PTHREAD_PROCESS_PRI-
       VATE.

       Attempts  to  initialize  previously initialized condition variable attributes object will leave the storage allocated by the previous ini-
       tialization unallocated.

       After a condition variable attributes object has been used to initialize one or	more  condition  variables,  any  function  affecting  the
       attributes object (including destruction) does not affect any previously initialized condition variables.

       The  pthread_condattr_destroy()	function destroys a condition variable attributes object; the object becomes, in effect, uninitialized. An
       implementation may cause pthread_condattr_destroy() to set the object referenced by attr to an invalid value. A destroyed  condition  vari-
       able  attributes  object  can be re-initialized using pthread_condattr_init(); the results of otherwise referencing the object after it has
       been destroyed are undefined.

       Additional attributes, their default values, and the names of the associated functions to get and set those attribute values are  implemen-
       tation-dependent.

       If  successful,	the  pthread_condattr_init() and pthread_condattr_destroy() functions return  0. Otherwise, an error number is returned to
       indicate the error.

       The  pthread_condattr_init() function will fail if:

       ENOMEM	       Insufficient memory exists to initialize the condition variable attributes object.

       The pthread_condattr_destroy() function may fail if:

       EINVAL	       The value specified by attr is invalid.
