Playing a tone

[Funkmaster P]

All I want to do is play a simple tone at varying frequencies, I searched through all of the help, and all I could find was DirectSound, wave-audio devices, and Midi support, isn't there just a simple function like:
void sound( int freq); !?!?!

FUNKMASTER P

IDirectSoundBuffer::SetFrequency
