PTHREAD_BARRIERATTR(3)     Library Functions Manual     PTHREAD_BARRIERATTR(3)

NAME
     pthread_barrierattr_init, pthread_barrierattr_destroy, -- barrier
     attribute operations

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <&lt;pthread.h>&gt;

     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 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.

SEE ALSO
     pthread_barrier_init(3)

STANDARDS
     Both functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
