I'm trying to implement generix functions for Queue manager connection and other functions...
I gave prototype as void CMQCONNX (MQCHAR48, MQCNO *, MQHCONN *, MQLONG *, MQLONG *);
I called the function in main as CMQCONNX (QMName,&Connect_options,&Hcon,&CompCode,&CReason)
Within the used defined function I have to call the function to create connection..I called the following function statement
MQCONNX (QMName,&Connect_options,&Hcon,&CompCode,&CReason);
I got Error as
1. C:\Dev-Cpp\Programs\New Folder\Pointer Trigger Monitor\triggermonitor.c cannot convert `MQCNO**' to `MQCNO*' for argument `2' to `void MQCONNX (MQCHAR*, MQCNO*, MQHCONN*, MQLONG*, MQLONG*)'
Please look at error and suggest...I'm also trying... |

Hi,

That's pretty self explanitory, MQCNO** is a double pointer and MQCNO* is a single pointer.
This is not a MQ error but standard C coding error. Just review pointers in C programming, any good text should have a chapter on this subject.

Connect_options is already a pointer passed into CMQCONNX, so you do not need to pass its address to MQCONNX. The same thing applies to Hcon, CompCode and CReason. The correct call in your code is
| Code: |
MQCONNX (QMName,Connect_options,Hcon,CompCode,CReason);
|
[/code] |
