[Info-vax] MQ series client support AST?

[rockdale]

Jan-Erik:


Thanks for your reply.

Right now I have a while loop to read  (MQGET) from MQ server and it
works fine.

Our customer does not like this polling idea (read the MQ in a while
loop) and they asked if it is possible to change to use AST. Like TCP/
IP socket communication when we call sys$qiow to read from the socket,
when the socket buffer has new data it will tigger the AST routine and
we will handle the data from there.

What I am asking is does MSQ series client also has such mechanism
when a new message is ready, my application will get an ast and we
will read the new message, instead of keeping read the MQ for a new
message.

Again, thanks
-Rockdale
