Thanks!

How about if I had this:
Code:
"real 449m8.133s"

And I wanted to substring it to only make it:
Code:
"449m8.133s"

Thanks again!

NAME
PCRE - Perl-compatible regular expressions SYNOPSIS
#include <pcre.h> int pcre_get_named_substring(const pcre *code, const char *subject, int *ovector, int stringcount, const char *stringname, const char **stringptr); DESCRIPTION
This is a convenience function for extracting a captured substring by name. The arguments are: code Compiled pattern subject Subject that has been successfully matched ovector Offset vector that pcre_exec() used stringcount Value returned by pcre_exec() stringname Name of the required substring stringptr Where to put the string pointer The memory in which the substring is placed is obtained by calling pcre_malloc(). The convenience function pcre_free_substring() can be used to free it when it is no longer needed. The yield of the function is the length of the extracted substring, PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string name is invalid. There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page. ATTRIBUTES
