Now that's truly weird. It's saying that the comparison is of always zero
values, but the actual report lines have:
Host IP Address Data Sent Data Rcvd
212.97.170.63 212.97.170.63 60 0.0 % 0 0.0 %
Has non-zero values...
This might be a total tangent, but what version of gcc are you running?
I had you put %llu in the traceEvent() lines, because there's a gcc 'issue'
(they swear it's not a bug):
When you pass stuff to printf() it gets passed as pointers or as full word
(4 byte) values. Then based on the format spec, it's pulled off the stack
and interpreted. However, a long long is 8 bytes, but with a %d
specification it's only pulls off the 4bytes, leaving a 'stray' 4 byte
value/pointer.
So while you can usually get away with ignoring the l format specifier, if
you don't have it for long longs it's trouble. This leads to the expected
albeit IMO nonsense output (the (null) comes from the extra 4 bytes):
$ ./gcc_322_unsignedlonglong_testprogram
# c 1 - nonsense
# c 2 - nonsense
# c 3 - nonsense
# c 577732784177545220
# c 1 - (null) stuff
# c 2 - (null) stuff
# c 3 - (null) stuff
# c 4 - stuff
>From this test program:
int main(int argc, char *argv[]) {
unsigned long long ullCount;
unsigned long ulCount;
ulCount = 1;
printf("# c %d - %s\n", ulCount, "nonsense");
ulCount++;
printf("# c %u - %s\n", ulCount, "nonsense");
ulCount++;
printf("# c %lu - %s\n", ulCount, "nonsense");
ulCount++;
printf("# c %llu\n", ulCount, "nonsense");
ullCount = 1;
printf("# c %d - %s %s\n", ullCount, "stuff");
ullCount++;
printf("# c %u - %s %s\n", ullCount, "stuff");
ullCount++;
printf("# c %lu - %s %s\n", ullCount, "stuff");
ullCount++;
printf("# c %llu - %s\n", ullCount, "stuff");
}
(Cut & paste the code into a file, say x.c and compile it thus:
$ gcc -o x x.c
$ ./x
And let me know. If you're not using an older gcc which doesn't have this
'issue', then I don't see how the comparison could be reporting 0s.
