I've been able to find instructions on how to create a hello world
C-external but not one that creates a simple sine wave from a sinewave
equation like A*sin(w*t+p)
(https://secure.wikimedia.org/wikipedia/en/wiki/Sine_wave) Does anyone
have one or know where to find one.
The canonical reference is here:

You just need to plug your equation into the perform routine.
Also check the source for osc~ in d_osc.c of the Pd source, which uses a
fancy 32-bit float cosine table scanning method that was useful when it
mattered but is getting obsolete as a call to sin() is probably just as
fast nowadays.
