DESCRIPTION
Barrier attributes are used to specify parameters to be used with
pthread_barrier_init(3). One attribute object can be used in multiple calls to
pthread_barrier_init(), with or without modifications between calls.
The pthread_barrierattr_init() function initializes attr with the default barrier attributes.
The pthread_barrierattr_destroy() function destroys attr.
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
No error codes are defined for
pthread_barrierattr_init().
The pthread_barrierattr_destroy() function may fail if:
-
[EINVAL]
-
The value specified by attr is invalid.
STANDARDS
