I am attempting to use VMS mailboxes to let a subprocess communicate with my application. What I basically want to do is grab the output from the process (from the mailbox) and put it into a motif text widget. I am using an AST (asynchronous system trap) to read from the mailbox whenever data is sent to the mailbox. My problem is that my interface basically stops processing events when my AST function starts getting called. Anything the user does is queued up but doesn't get processed until after the mailbox I/O is finished. I tried using XFlush and XSync before I read from the mailbox but that didn't help. I am using the SYS$QIO (no wait) to read from the mailbox. Thanks for the help! ----------------------------------------------------------------- Jon LeBlanc GenRad, Inc. jml@genrad.com 508/369-4400 x2918
