Hi Patrick,
Someone might correct me, but I don't believe that there is a way
to get a list of the PVs/IOC.  In linux, you can always take the database
ascii file and do a grep on "record".  That will give you a list of all
PVs for that IOC.

As for your second problem, one of my colleagues found this.
You need to add the following lines to add a hack to the alBeep()
function which uses a system command to play a sound file, e.g.:

/* Additional include */
#include <stdlib.h>

int alBeep(Display *displayBB)
{
    /* Additional 'beep' command */
    /* (needs error checking...) */
    system("play /path/to/beep.wav");

    XBell(displayBB, 0);
    return 0;
}
