<p>
Rewinds the filedescriptor to the current buffer position and blows 
the file read ahead buffer. This is useful for third party uses of
the scanners filedescriptor, which hooks onto the current scanning 
position.

<p>
Parses the next token, without removing it from the input stream.
The token data is placed in the
<em class="structfield"><code>next_token</code></em>,
<em class="structfield"><code>next_value</code></em>,
<em class="structfield"><code>next_line</code></em>, and
<em class="structfield"><code>next_position</code></em> fields of the <a class="link" href="glib-Lexical-Scanner.html#GScanner"><span class="type">GScanner</span></a> structure.
</p>
<p>
Note that, while the token is not removed from the input stream (i.e.
the next call to <a class="link" href="glib-Lexical-Scanner.html#g-scanner-get-next-token"><code class="function">g_scanner_get_next_token()</code></a> will return the same token),
it will not be reevaluated. This can lead to surprising results when
changing scope or the scanner configuration after peeking the next token.
Getting the next token after switching the scope or configuration will
return whatever was peeked before, regardless of any symbols that may
have been added or removed in the new scope.
