Trapping Broadcasts in Detached Processes?

» close window

The Question is:

 
Is it possible to trap a broadcast message in a detached process?  I'd like to
 trap the mail message announcement.  Thank you!

The Answer is :

 
 
  You will need to code the application to acquire a terminal device,
  to associate a mailbox with the terminal (possibly via a call to
  lib$asn_with_mbx), and trap the messages there -- among the easiest
  ways to acquire a terminal is via the pseudo-terminal API (see the
  I/O User's Reference Manual), though there are other ways.
 
  The AskQ area (referenced in the FAQ) has some related examples:

  Topic (1554) is also potentially related.
