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);

       int pcre16_get_named_substring(const pcre16 *code,
            PCRE_SPTR16 subject, int *ovector,
            int stringcount, PCRE_SPTR16 stringname,
            PCRE_SPTR16 *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[16]_exec() used
         stringcount   Value returned by pcre[16]_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[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 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.
