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);

       int pcre32_get_substring(PCRE_SPTR32 subject, int *ovector,
            int stringcount, int stringnumber,
            PCRE_SPTR32 *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|32]_exec() used
         stringcount   Value returned by pcre[16|32]_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|32]_malloc().
       The convenience function pcre[16|32]_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.
