Argument

 

facility_index

   OpenVMS usage:longword_unsigned
   type:         longword (signed)
   access:       read only
   mechanism:    by reference
   Represents an index of the asynchronous action. This index is
   used with the TPU$TRIGGER_ASYNC_ACTION routine to let TPU know
   what action to perform. It may also be used to delete an action
   routine (by omitting the tpu_statement). You may register several
   asynchronous actions depending on your application's needs. This
   facility index number may be any positive integer.
 

tpu_statement

   OpenVMS usage:char_string
   type:         character string
   access:       read only
   mechanism:    by descriptor
   The TPU statement you want executed when you call the
   TPU$TRIGGER_ASYNC_ACTION routine. The statement is compiled and
   then stored internally. If you omit the parameter, TPU removes
   the action from its list of asynchronous events.
