DESCRIPTION
This routine unlocks the DECthreads global mutex. Because the global mutex is recursive, the unlock occurs when each call to
tis_lock_global(3) has been matched by a call to this routine. For example, if your program called tis_lock_global(3) three times,
tis_unlock_global(3) unlocks the global mutex when you call it the third time.
For more information about actions taken when threads are present, refer to the pthread_unlock_global_np()(3) description.
RETURN VALUES
