Hi,
In C we have just 1 header file cmqc.h.
But why do we have so many header files in C++ ?
Can somebody pls explain ?
And I am thinking we can just include all the header files in 1 header file say, xyz.hpp and just include it in every C++ MQ application program.
Any suggestions ... ?
Thanks.

This is a meaningless thing to worry about.

It really depends on how you are doing the MQ programming that would dictate which header file(s) one would need. If you do just the native calls like MQGET and MQPUT, then you most likely will get by with what's in cmqc.h. If you use some other API's, then there are other header files that are required.

For the same reason that the C/C++ runtime libraries don't have just a single header file to include - You've got string.h, stdlib.h, memory.h, iostream.h, iostream, vector and more etc. etc.  .
You don't have to create your own header file to include them all, just include imqi.hpp and that will include them all for you.

Actually, that was my question.
If I include imqi.hpp in my C++ programs does it have everything that is there in the other MQ/C++ header files ? Do I have to include any other MQ/C++ headers in my program ?
Thanks.

Again, it depends what you are doing. Some methodologies only require certain headers. But, if you're the lazy type and don't want to bother learning any of that, then you can include imqi.hpp and you will get everything.

I think the C++ programmer's guide tells you what gets included or not by which header files.

Follow the example in the sample program imqsput.cpp:
| Code: |
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <imqi.hpp> // WebSphere MQ MQI |
