PTHREAD_BARRIERATTR(3)  NetBSD Library Functions Manual PTHREAD_BARRIERATTR(3)

NAME
     pthread_barrierattr_init, pthread_barrierattr_destroy, -- barrier
     attribute operations

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_barrierattr_init(pthread_barrierattr_t *attr);

     int
     pthread_barrierattr_destroy(pthread_barrierattr_t *attr);

DESCRIPTION
     Barrier attributes are used to specify parameters to
     pthread_barrier_init().  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 all 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
     pthread_barrierattr_init() shall fail if:

     [ENOMEM]           Insufficient memory exists to initialize the barrier
                        attributes object.

     pthread_barrierattr_init() may fail if:

     [EINVAL]           The value specified by attr is invalid.

     pthread_barrierattr_destroy() may fail if:

     [EINVAL]           The value specified by attr is invalid

STANDARDS
     pthread_barrierattr_init() and pthread_barrierattr_destroy() conform to
     IEEE Std 1003.1-2001 (``POSIX.1'').
