Synopsis

   cc [options] -Kthread file
   
   #include <synch.h>
   

   int _barrier_spin_destroy(barrier_spin_t *barrier);

Description

_barrier_spin_destroy destroys the barrier pointed to by barrier. This includes invalidating the barrier and freeing any associated implementation-allocated dynamic resources.

Any user-allocated dynamic storage is unaffected by _barrier_spin_destroy and must be explicitly released by the program.

Parameters

barrier: pointer to barrier to be destroyed

Return values

_barrier_spin_destroy returns zero for success and an error number for failure.

Errors

If one of the following conditions is detected, _barrier_spin_destroy returns the corresponding value:

EBUSY: a thread is still spinning at the barrier
EINVAL: invalid argument specified
