tis_unlock_global - Unlocks the DECthreads global mutex
Standard C Library (libc.so, libc.a)
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.
If an error condition occurs, this routine returns an
integer value indicating the type of error. Possible
return values are as follows: Successful completion. The
DECthreads global mutex is unlocked or locked by another
