Arguments

 

event-id

   OpenVMS usage identifier
   type          longword (unsigned)
   access        write only
   mechanism     by reference
   Identifier of the event. The event-id argument is the address of
   an unsigned longword containing the identifier. Event-id must be
   used in other calls to identify the event.
 

event-name

   OpenVMS usage char_string
   type          character string
   access        read only
   mechanism     by descriptor
   Name of the event. The event-name argument is the address of a
   descriptor pointing to a character string containing the event
   name. The name of the event is entirely arbitrary. If you do
   not specify a value for event-name, or if you specify 0, a new
   unnamed event is created, which can be referenced only by its
   identifier. An arbitrary number of unnamed events can be created
   by a given application.
