NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS


       #include <pcre.h>

       int pcre_get_substring(const char *subject, int *ovector,
            int stringcount, int stringnumber,
            const char **stringptr);

       int pcre16_get_substring(PCRE_SPTR16 subject, int *ovector,
            int stringcount, int stringnumber,
            PCRE_SPTR16 *stringptr);

DESCRIPTION


       This is a convenience function for extracting a captured substring. The arguments are:

         subject       Subject that has been successfully matched
         ovector       Offset vector that pcre[16]_exec() used
         stringcount   Value returned by pcre[16]_exec()
         stringnumber  Number of the required substring
         stringptr     Where to put the string pointer

       The  memory  in  which  the substring is placed is obtained by calling pcre[16]_malloc(). The convenience
       function pcre[16]_free_substring() can be used to free it when it is no longer needed. The yield  of  the
       function  is the length of the substring, PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained,
       or PCRE_ERROR_NOSUBSTRING if the string number 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.
