SYNOPSIS
 

#include &#60;pcre.h&#62;


int pcre_get_substring(const char *subject, int *ovector,
int stringcount, int stringnumber,
const char **stringptr);


int pcre16_get_substring(PCRE_SPTR16 subject, int *ovector,
int stringcount, int stringnumber,
PCRE_SPTR16 *stringptr);


int pcre32_get_substring(PCRE_SPTR32 subject, int *ovector,
int stringcount, int stringnumber,
PCRE_SPTR32 *stringptr);

 
DESCRIPTION
 

This is a convenience function for extracting a captured substring. The
arguments are:
<pre>
 subject Subject that has been successfully matched
 ovector Offset vector that pcre[16|32]_exec() used
 stringcount Value returned by pcre[16|32]_exec()
 stringnumber Number of the required substring
 stringptr Where to put the string pointer
</pre>
The memory in which the substring is placed is obtained by calling
pcre[16|32]_malloc(). The convenience function
pcre[16|32]_free_substring() can be used to free it when it is no longer
needed. The yield of the function is the length of the substring,
PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or
PCRE_ERROR_NOSUBSTRING if the string number is invalid.


There is a complete description of the PCRE native API in the
<a href="pcreapi.html">pcreapi</a>
page and a description of the POSIX API in the
<a href="pcreposix.html">pcreposix</a>
page.
