<DT><B> Usage </B><DD><P><CODE>void SLang_exit_error (char *fmt, ...)</CODE>
<DT><B> Description </B><DD><P>The <CODE>SLang_exit_error</CODE> function terminates the program and
displays an error message using a <CODE>printf</CODE> type variable
argument list.  The default behavior to this function is to write
the message to <CODE>stderr</CODE> and exit with the <CODE>exit</CODE> system
call. 
<P>If the the function pointer <CODE>SLang_Exit_Error_Hook</CODE> is
non-NULL, the function to which it points will be called.  This
permits an application to perform whatever cleanup is necessary.
This hook has the prototype:
<BLOCKQUOTE><CODE>
<PRE>
     void (*SLang_Exit_Error_Hook)(char *, va_list);
