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 yield 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 API in the pcreapi page.
