SYNOPSIS
       int  dgsemgetid (void)

       semaphores, the original base identifier is returned.

       Once allocated, a thread in the process is allowed to pend on any
       semaphore in the set.

RETURN VALUE
       base id   A non-negative integer that identifies the base id of the
                 the semaphore set.

DIAGNOSTICS
       The call always returns successfully.
