I'm trying to use patterns.c for some pattern matching. The manual
mentions captures using "()" around what you want to capture. I don't
see how to get at the data though. Here is a sample program.
#include <stdio.h>
#include "patterns.h"
int
main(int argc, char *argv[])
{
const char *errstr = NULL;
const char *string = "the quick the brown the fox";
const char *pattern = "the";
int ret;
struct str_match match;
ret = str_match(string, pattern, &match, &errstr);
if (errstr != NULL)
printf("%s\n", errstr);
else
printf("number of matches %d\n", match.sm_nmatch);
return 0;
}
It prints 2 which I was expecting 3. I've tried multiple other patterns
and it seems the answer is always 2. Which leads me to believe I'm doing
something wrong. Any assistance appreciated.
Thanks,
Edgar
