MQLONG is 4 bytes
Filling in time...
| Code: |
#include <cmqc.h>
void main() {
printf("Len MQMD : %d\n", sizeof(MQMD));
printf("Len XQH : %d\n", sizeof(MQXQH));
} |
Len MQMD : 364
Len XQH : 428 |

Jason,
thanks!!!
so the total header for each and every message going to another Qmgr is 364+428 = 792 bytes.
So the 758 number I had in my head dates back a couple of years so I'll subtract 40... 
and end up with 752 ... only off by 6 bytes... (no need for new memory after all...)

I went back at my program notes and saw that even though the program was originally compiled with the version 1 MQMD, I had planned for the version 2 just in case, and made the hold area big enough to accomadate either one. Sorry for the confusion. Looking at it quickly yesterday, I saw the hold area, saw the Version 1 copybook, and assumed they were equal. Hey, its been a few years since I even saw the program. I'm amazed I was able to even to find the thing!

Hellow,
MQXQH includes the message descriptor structure MQMD, so the total size of the message payload is "only" the size of MQXQH.
Anybody can confirm this ?
I want to determine the total overhead of a message to calculate a network link size.
Thanks. |
