DESCRIPTION

28
29       This  is  a convenience function for extracting a captured substring by
30       name. The arguments are:
31
32         code          Compiled pattern
33         subject       Subject that has been successfully matched
34         ovector       Offset vector that pcre[16|32]_exec() used
35         stringcount   Value returned by pcre[16|32]_exec()
36         stringname    Name of the required substring
37         stringptr     Where to put the string pointer
38
39       The memory in which the substring is  placed  is  obtained  by  calling
40       pcre[16|32]_malloc().  The  convenience  function pcre[16|32]_free_sub‐
41       string() can be used to free it when it is no longer needed. The  yield
42       of   the   function   is   the   length  of  the  extracted  substring,
43       PCRE_ERROR_NOMEMORY if sufficient memory  could  not  be  obtained,  or
44       PCRE_ERROR_NOSUBSTRING if the string name is invalid.
45
46       There  is  a complete description of the PCRE native API in the pcreapi
47       page and a description of the POSIX API in the pcreposix page.
