* 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).
