  • Subject: QMHRDQM API - Retrieve Data Queue Message
  • From: Mark Drazic <Mark.Drazic@xxxxxxxxxxxx>
  • Date: Thu, 14 Dec 2000 11:40:38 -0600

I am unable to get this API to return the pointer for the Receiver Variable
(1st parm).  Whether I send a *NULL pointer, or an already allocated one,
the API always returns the pointer as *NULL.  All other parms appear to be
correct, there are no error messages issued by the API, and entries do exist
on the Queue based on the results from the QMHQRDQD API.  If I can't use a
pointer, I am limited to a field size of 32,767 for all the Data Queue
entries, which will probably not be workable.  

Is there some trick to getting this to work?  I am calling the API from a
Service Program in an Activation Group called QSRV, could this be affecting
the results?  I have noticed this problem in calling other IBM API's, and
RPG ILE needs to be able to receive pointer information for these types of
functions.

Any help would be greatly appreciated.
