SYNOPSIS

10       #include <pcre.h>
11
12       int pcre_copy_named_substring(const pcre *code,
13            const char *subject, int *ovector,
14            int stringcount, const char *stringname,
15            char *buffer, int buffersize);

DESCRIPTION

18
19       This  is  a  convenience  function for extracting a captured substring,
20       identified by name, into a given buffer. The arguments are:
21
22         code          Pattern that was successfully matched
23         subject       Subject that has been successfully matched
24         ovector       Offset vector that pcre_exec() used
25         stringcount   Value returned by pcre_exec()
26         stringname    Name of the required substring
27         buffer        Buffer to receive the string
28         buffersize    Size of buffer
29
30       The yield is the length of the substring,  PCRE_ERROR_NOMEMORY  if  the
31       buffer  was  too small, or PCRE_ERROR_NOSUBSTRING if the string name is
32       invalid.
33
34       There is a complete description of the PCRE native API in  the  pcreapi
35       page and a description of the POSIX API in the pcreposix page.
