Teresa,
There is some code in the MO01 Support Pack that uses the Pre-Processor
macros to take most of the work out of this. The macro looks like this:
/*********************************************************************/
/* */
/* define some macros to print out the parameters */
/* */
/*********************************************************************/
#define PRINTPARAM(param) \
case param: \
{ \
char *p = #param; \
strncpy(thestring,pmqcfst->String,min(sizeof(thestring), \
pmqcfst->StringLength)); \
thestring[pmqcfst->StringLength] = '\0'; \
printf("%s %s\n",p,thestring); \
} \
break;
Then the code looks like this...
/*********************************************************************/
/* print a string parameter */
/*********************************************************************/
void printfmqcfst(MQCFST* pmqcfst)
{
char thestring[100];
switch (pmqcfst->Parameter)
{
PRINTPARAM(MQCA_APPL_ID)
// many iterations deleted here...
.
.
.
default:
printf("Invalid parameter, %ld\n",pmqcfst->Parameter);
break;
}
}
Of course, extracting all the defines from the header file and keeping it
current is the trick. I'm attaching a Perl program that will do this for
you. If you decide to use this coding technique, I would suggest using the
Perl program to generate a file that you then #include into the C++ code.
Then set up 'make' to run the Perl script as necessary to pick up the latest
defines if /opt/mqm/inc/cmqc.h ever changes.
Since the code in MSO01 was not directly applicable, I had the Perl program
write out a simpler, albeit untested, subroutine. It's just a starting
point, change as necessary.

open(HDR, "/opt/mqm/inc/cmqc.h") or die("Cannot find cmqc.h file\n");
my @Lines = <HDR>;
close HDR;
# Captures Reason Codes and Feedback codes
@Lines = grep(/#define ?(MQRC_| MQFB_)/, @Lines);
print <<EOF
#define PRINTPARAM(param) \
case param: \
printf("%s: '%s'\n", #param, mqrc) \
break;
#endif
/*********************************************************************/
/* print a string parameter */
/*********************************************************************/
void printrc(int mqrc)
{
switch (mqrc)
{
EOF
;
foreach (sort(@Lines)) {
s/^\s+//g; # Delete leading spaces
print " PRINTPARAM(", (split(/\s+/))[1], ")\n";
}
print <<'EOF'
default:
printf("Invalid parameter, %ld\n",mqrc);
break;
}
}
EOF
;
exit;

Subject: MQ reasonCode
Can someone show me some sample C++ code to
translate the MQ reason code into some kind of readable text format.
Thanks!
