The system utility gPlaySound() attempts to sound a note using hardware system sound resources if available. If a note of the specified frequency and/or time is not possible (e.g. under UNIX and OpenVMS), a simple 'BEEP' may be sounded by the system.

gPlaySound(-MB_ICONHAND,0)

gPlaySound(-16,0)
will play the System Asterisk entry in the [sounds] section of WIN.INI. Other values include:
