|
|
|
<P>
|
|
This is a convenience function for extracting a captured substring, identified
|
|
by name, into a given buffer. The arguments are:
|
|
<P>
|
|
<BR> <I>code</I> Pattern that was successfully matched
|
|
<BR> <I>subject</I> Subject that has been successfully matched
|
|
<BR> <I>ovector</I> Offset vector that <B>pcre[16|32]_exec()</B> used
|
|
<BR> <I>stringcount</I> Value returned by <B>pcre[16|32]_exec()</B>
|
|
<BR> <I>stringname</I> Name of the required substring
|
|
<BR> <I>buffer</I> Buffer to receive the string
|
|
<BR> <I>buffersize</I> Size of buffer
|
|
<P>
|
|
The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was
|
|
too small, or PCRE_ERROR_NOSUBSTRING if the string name 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
