When I run the below code I don't get any error but the property is not inserted into my Message Handle... This is on Linux Red Hat in 'C'.
memset(pPropName, 0x00, sizeof(PropName));
memset(pPropValue, 0x00, sizeof(PropValue));
memcpy(pPropName, Property4Name, strlen(Property4Name));
CHARV.VSLength = strlen(Property4Name);
Type = MQTYPE_NULL;
ValueLength = 0;
MQSETMP(HCONN, HMSG, &SMPO, &CHARV, &PD, Type, ValueLength, pPropValue, &mqcc, &mqrsn);
if (mqcc)
{
printf("mqputWithProperty, (4) MQSETMP completion code[%d], reason code[%d]\n", mqcc, mqrsn);
return;
}
Any clue?

| Use NULL directly not pPropValue in the SETMP call |

Already did that and got the same result.
I always get a Completion code of 0 and a reason code of 0, but the property is not added...

Did you issue the MQCRTMH (Create Message Handle) MQ API call before issuing MQSETMP MQ API call?
There is an IBM MQ sample called amqsstma.c that you should have a look at and model your code after.

Yes I did.
My test program does create one property for each property type. The only one that does not work properly is for MQTYPE_NULL. The property does not get created in the message handle. All others are present.

Sounds like a defect then, since the documentation appears to suggest what you have done should work. You should raise a case with IBM
