  • Subject: Virtual Terminals and Data Queues

Hello,

Does any one (IBM lurkers prefereably) know why the Virtual Terminal APIs 
ignore the SENDERID 
attribute on a data queue?

Background:
===========
A data queue is named on the Open Virual Terminal API.  If the this data queue 
is created with 
SENDERID(*NO) then all is fine.  If the data queue is created with 
SENDERID(*YES) then things 
are __not__ fine.  What is __supposed__ to happen is that the enqueued message 
is offset by 36 
bytes allowing sender information to appear in those bytes.  What actually 
happens is that the 
VT APIs simply enqueue the message at offset 0 and ignore the sender 
information.

The problem is that the Receive Data Queue API, which is the method for getting 
the queue entry, 
__does__ respect the SENDERID attribute and will think the first 36 bytes 
contains sender 
information and so does not return the enqueued message properly.

Regards,
Simon Coulter.
