<DT><B> Usage </B><DD><P><CODE>int SLang_input_pending (int tsecs)</CODE>
<DT><B> Description </B><DD><P><CODE>SLang_input_pending</CODE> may be used to see if an input character
is available to be read without causing <CODE>SLang_getkey</CODE> to block.
It will wait up to <CODE>tsecs</CODE> tenths of a second if no characters
are immediately available for reading.  If <CODE>tsecs</CODE> is less than
zero, then <CODE>SLang_input_pending</CODE> will wait <CODE>-tsecs</CODE>
milliseconds for input, otherwise <CODE>tsecs</CODE> represents <CODE>1/10</CODE>
of a second intervals.
