FN_SEMSIG()
 Signal a semaphore (increment)
------------------------------------------------------------------------------
 Syntax
 
      fn_semSig( <nHandle> ) -> nRc
 
 Arguments

     <nHandle> is the semaphore handle, returned from a previous call
     to fn_semOpen().

 Returns

     nRc, a numeric, as follows

          0 - success
          1 - semaphore overflow ( value > 127 )
        255 - invalid semaphore handle

 Description

      Use fn_semSig() when your app has finished with the resource
      locked by a semaphore.  This will increase the value (thus
      making a slot available to another app).

      For more information, see the description under fn_semOpen().

 Examples

      QOUT( "Signal returns: " + STR( fn_semSig( nHandle ) ) )
