while trying to open the MQ queue, my program is returning
| Quote: |
| MQOPEN ended with reason code 0 |
below the code which opens the MQ. What is the impact when Reason!=MQRC_NONE. Also during execution OpenCode is not failed.
Currently what happens is, while sending messages, its not reaching queue.
while putting message in the queue also it returns
| Quote: |
| MQPUT ended with reason code 0. |
Can anyone explain why is this happening?
My program is running in Aix 6.1 machine.

code for opening the Queue is below

| MQOO_FAIL_IF_QUIESCING /* but not if MQM stopping */
; /* = 0x2010 = 8208 decimal */
MQOPEN(.....);
if (Reason != MQRC_NONE)
printf("MQOPEN ended with reason code %d\n", Reason);
if (OpenCode == MQCC_FAILED)
printf("unable to open queue for output\n");
....
MQPUT(Hcon, /* connection handle */
Hobj, /* object handle */
&md, /* message descriptor */
&pmo, /* default options (datagram) */
messlen, /* message length */
buffer, /* message buffer */
&CompCode, /* completion code */
&Reason); /* reason code */
/* report reason, if any */
if (Reason != MQRC_NONE) {
printf("MQPUT ended with reason code %d\n", Reason);
}else
printf("MQPUT successfull");
}

Go to google. Search for MQRC_NONE. What does your research tell you about MQRC_NONE?
What does not failed mean to you?

I'm confused about the return code.
value of MQRC_NONE is '0', but when I print the value of reason it is also 0.
it should not enter
if (Reason != MQRC_NONE)
printf("MQOPEN ended with reason code %d", Reason);
but value printed is 0, |

What is the declared type for Reason? It should be MQLONG. |

| It is declared as MQLONG. |

Very strange. Try coding some diagnostics:
| Code: |
MQOPEN(.....)
printf("MQOPEN returned CompCode=%d Reason=%d\n", CompCode, Reason );
if (Reason != MQRC_NONE)
printf("MQOPEN ended with reason code %d\n", Reason); |
I doubt that %d is not printing a MQLONG as a 32 bit signed integer, or the printf is being executed even though the if ( ) should have failed, if ( 0 != 0 ). We need to dig a bit deeper to understand what is going on.

Is it possible that the posted code doesn't match what's running, or that the output in question is from a similar but separate printf?
What was the complete command used to compile the program, including compiler options, and library options?
To expand on gbaddelay's suggestion, try something like:
| Code: |
printf("Reason = %ld, size = %lu, MQRC_NONE = %ld, size = %lu, boolean = %d\n",
(long) (Reason), sizeof (Reason), (long) (MQRC_NONE), sizeof (MQRC_NONE), Reason != MQRC_NONE); |
