What are the characteristics of the message you are trying to retrieve? If it's an IBM supplied message what is the msgid? Your approach is correct and using some randomly picked msgids out of qcpfmsg my testing showed the correct Bytes Available being returned so it would appear to be something related to the definition of the msgd. Bruce Dave Murvin <davem@xxxxxxxx> Sent by: To midrange-l-bounce midrange-l@xxxxxxxxxxxx s@xxxxxxxxxxxx cc Subject 10/01/2004 04:46 Bytes Available not correct in API PM QMHRTVM Please respond to Midrange Systems Technical Discussion I am trying to use the RTVM0400 format of the QMHRTVM (Retrieve message) API and am not getting the expected results in the returned Bytes Available field (second field in the RTVM0400 format - field QMHBAVL14 in the QSYSINC copy file). Sequence of events is: 1. Allocate 8 bytes to the Message information input parm so I can get the first two fields in the RTVM0400 format and find out how big the message information is. 2. Call QMHRTVM for my particular message passing 8 in the Length of message info input parm. 3. RTVM0400 Bytes available field is 328 4. reallocate Message information input parm to hold 328 bytes 5. Call QMHRTVM again, passing new length available as 328 bytes (Length of message information input parm) 5. RVTM0400 Bytes available field is now 684 bytes! Bytes actually returned returned is 328 as expected. The problem is that, as I understand the APIs, the first call to QMHRTVM should have returned 684 bytes in the Bytes Available field. If I call QMHRTVM and allocate 3000 bytes on the first call, it does return the correct 684 bytes, but this does not seem to be the way it should work. I didn't see anything in the archives or on the IBM APAR site. I am at V5R3. Any suggestions?
