SYNOPSIS

9
10       #include <pcre.h>
11
12       int pcre_get_substring(const char *subject, int *ovector,
13            int stringcount, int stringnumber,
14            const char **stringptr);

DESCRIPTION

17
18       This is a convenience function for extracting a captured substring. The
19       arguments are:
20
21         subject       Subject that has been successfully matched
22         ovector       Offset vector that pcre_exec() used
23         stringcount   Value returned by pcre_exec()
24         stringnumber  Number of the required substring
25         stringptr     Where to put the string pointer
26
27       The memory in which the substring is  placed  is  obtained  by  calling
28       pcre_malloc().  The  convenience  function pcre_free_substring() can be
29       used to free it when it is no longer needed. The yield of the  function
30       is  the length of the substring, PCRE_ERROR_NOMEMORY if sufficient mem‐
31       ory could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string num‐
32       ber is 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.
