 * Name: PDC_beep
 *
 * Description:
 *   Emits a short audible beep.  If this is not possible on your platform,
 *   you must set SP->audible to false during initialization (i.e., from
 *   PDC_scr_open() -- not here); otherwise, set it to true.  This function
 *   is called from beep().
 *

/****************************************************************************
 * Name: PDC_napms
 *
 * Description:
 *   This is the core delay routine, called by napms().  It pauses for about
 *   (the X/Open spec says "at least") ms milliseconds, then returns.  High
 *   degrees of accuracy and precision are not expected (though desirable, if
 *   you can achieve them).  More important is that this function gives back
 *   the process time slice to the OS, so that PDCurses idles at low CPU
 *   usage.

/****************************************************************************
 * Name: PDC_sysname
 *
 * Description:
 *   Returns a short string describing the platform, such as "DOS" or "X11".
 *   This is used by longname(). It must be no more than 100 characters; it
 *   should be much, much shorter (existing platforms use no more than 5).
