NAME    [Toc]    [Back]

     pthread_condattr_init, pthread_condattr_destroy - initialize/destroy a
     condition variable	attribute object

C SYNOPSIS    [Toc]    [Back]

     #include <pthread.h>

     int pthread_condattr_init(pthread_condattr_t *attr);
     int pthread_condattr_destroy(pthread_condattr_t *attr);

DESCRIPTION    [Toc]    [Back]

     The function pthread_condattr_init() initializes the condition variable
     attribute object referenced by attr to the	default	attribute values.  The
     default sharing value is PTHREAD_PROCESS_PRIVATE.

     Once a condition variable attribute object	is used	to initialize one or
     more mutexes, any function	that affects the attribute object will not
     affect the	previously initialized mutexes.	 pthread_condattr_destroy()
     uninitializes the condition variable attribute structure referenced by
     attr.  This may include freeing dynamically allocated memory.

DIAGNOSTICS    [Toc]    [Back]

     These routines return zero.
