Name

pthread_barrierattr_destroy, pthread_barrierattr_init - destroy +and initialize the barrier attributes object (ADVANCED REALTIME +THREADS) +

Synopsis

#include <pthread.h> +

int pthread_barrierattr_destroy(pthread_barrierattr_t *attr); +
int pthread_barrierattr_init(pthread_barrierattr_t *attr); + +

Description

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. +

Results are undefined if pthread_barrierattr_init is called +specifying an already initialized attr attributes object. +

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. +

Return Value

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. +

Errors

The pthread_barrierattr_destroy function may fail if: +

EINVAL +: + The value specified by attr is invalid. +

+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. +

Examples

None. +

Application Usage

The pthread_barrierattr_destroy and +pthread_barrierattr_init functions are part of the Barriers +option and need not be provided on all implementations. +

Pthreads-w32 defines _POSIX_BARRIERS to indicate +that these routines are implemented and may be used.

Rationale

None. +

Future Directions

None. +
