DESCRIPTION
|
|
</b><br>
|
|
<P>
|
|
This is a convenience function for extracting a captured substring. The
|
|
arguments are:
|
|
<pre>
|
|
<i>subject</i> Subject that has been successfully matched
|
|
<i>ovector</i> Offset vector that <b>pcre_exec()</b> used
|
|
<i>stringcount</i> Value returned by <b>pcre_exec()</b>
|
|
<i>stringnumber</i> Number of the required substring
|
|
<i>stringptr</i> Where to put the string pointer
|
|
</pre>
|
|
The memory in which the substring is placed is obtained by calling
|
|
<b>pcre_malloc()</b>. The convenience function <b>pcre_free_substring()</b> 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.
