<p>
This is a convenience
function for extracting a captured substring. The arguments are: <p>
<i>subject</i>
Subject that has been successfully matched<br>
<i>ovector</i> Offset vector that <b>pcre_exec()</b> used<br>
<i>stringcount</i> Value returned by <b>pcre_exec()</b><br>
<i>stringnumber</i> Number of the required substring<br>
<i>stringptr</i> Where to put the string pointer<br>
<p>
The memory in which the substring is placed is obtained by calling <b>pcre_malloc()</b>.
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. <p>
There is a complete description of the PCRE
native API in the <b>pcreapi</b> page and a description of the POSIX API in
the <b>pcreposix</b> page. <p>
