<DT><B> Synopsis </B><DD><P>Initialize the <CODE>SLsmg</CODE> routines
<DT><B> Usage </B><DD><P><CODE>int SLsmg_init_smg (void)</CODE>
<DT><B> Description </B><DD><P>The <CODE>SLsmg_init_smg</CODE> function initializes the <CODE>SLsmg</CODE> screen
management routines.   Specifically, this function allocates space
for the virtual display and calls <CODE>SLtt_init_video</CODE> to put the
terminal's physical display in the proper state.  It is up to the
caller to make sure that the <CODE>SLtt</CODE> routines are initialized via
<CODE>SLtt_get_terminfo</CODE> before calling <CODE>SLsmg_init_smg</CODE>.
<P>This function should also be called any time the size of the
physical display has changed so that it can reallocate a new virtual
display to match the physical display.
<P>It returns zero upon success, or <CODE>-1</CODE> upon failure.
