<p>This function behaves like one of the basic arithmetic extractors, in that it also constructs a sentry object and has the same error handling behavior.</p>
<p>If <code>__sb</code> is NULL, the stream will set failbit in its error state.</p>
<p>Characters are extracted from this stream and inserted into the <code>__sb</code> streambuf until one of the following occurs:</p>
<ul>
<li>the input stream reaches end-of-file,</li>
<li>insertion into the output buffer fails (in this case, the character that would have been inserted is not extracted), or</li>
<li>an exception occurs (and in this case is caught)</li>
</ul>
<p>If the function inserts no characters, failbit is set. </p>

<p>This function returns a unique integer every time it is called. It can be used for any purpose, but is primarily intended to be a unique index for the iword and pword functions. The expectation is that an application calls xalloc in order to obtain an index in the iword and pword arrays that can be used without fear of conflict.</p>
<p>The implementation maintains a static variable that is incremented and returned on each invocation. xalloc is guaranteed to return an index that is safe to use in the iword and pword arrays. </p>
