_spin_destroy(3synch)                          _spin_destroy(3synch)


       NAME
             _spin_destroy - destroy a spin lock

       SYNOPSIS
             cc [options] -Kthread file
             #include <synch.h>
             int _spin_destroy(spin_t *lock);

          Parameters
             lock   pointer to spin lock to be destroyed

       DESCRIPTION
             _spin_destroy destroys the spin lock pointed to by lock.  This
             includes invalidating lock and freeing any associated
             implementation-allocated dynamic resources.

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

          Return Values
             _spin_destroy returns zero for success and an error number for
             failure, as described below.

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

             EBUSY    lock is locked by another thread.

             EINVAL   Invalid argument specified.
