PTHREAD..._DESTROY(3P) POSIX Programmer's Manual PTHREAD..._DESTROY(3P)
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
pthread_barrierattr_destroy, pthread_barrierattr_init — destroy
and initialize the barrier attributes object
#include <pthread.h>
int pthread_barrierattr_destroy(pthread_barrierattr_t *attr);
int pthread_barrierattr_init(pthread_barrierattr_t *attr);
The pthread_barrierattr_destroy() function shall destroy a
barrier attributes object. A destroyed attr attributes object can
be reinitialized using pthread_barrierattr_init(); the results of
otherwise referencing the object after it has been destroyed are
undefined. An implementation may cause
pthread_barrierattr_destroy() to set the object referenced by
attr to an invalid value.
The pthread_barrierattr_init() function shall initialize a
barrier attributes object attr with the default value for all of
the attributes defined by the implementation.
If pthread_barrierattr_init() is called specifying an already
initialized attr attributes object, the results are undefined.
After a barrier attributes object has been used to initialize one
or more barriers, any function affecting the attributes object
(including destruction) shall not affect any previously
initialized barrier.
The behavior is undefined if the value specified by the attr
argument to pthread_barrierattr_destroy() does not refer to an
initialized barrier attributes object.
If successful, the pthread_barrierattr_destroy() and
pthread_barrierattr_init() functions shall return zero;
otherwise, an error number shall be returned to indicate the
error.
The pthread_barrierattr_init() function shall fail if:
ENOMEM Insufficient memory exists to initialize the barrier
attributes object.
These functions shall not return an error code of [EINTR].
The following sections are informative.
None.
None.
If an implementation detects that the value specified by the attr
argument to pthread_barrierattr_destroy() does not refer to an
initialized barrier attributes object, it is recommended that the
function should fail and report an [EINVAL] error.
None.
