I can't remember how to pass multiple arguments to an external. I need
to pass any number of float arguments. I think it goes something like
void external_tilde_new(float *f_args, float num_args)
I've been searching thru the cvs repo to see if I can find an example,
but I haven't found one yet. Any suggestions?
you need to instruct class_new or class_addcreator what your argument list
is going to look like. If you have one float arg, end it like "A_FLOAT,0)"
but if you have two, then end it like "A_FLOAT,A_FLOAT,0)". However, if
you have a large number or variable number of them, do it like
"A_GIMME,0)" and use a method signature like:
t_pd *blah_new(t_symbol classname, int argc, t_atom *argv)
but then you have to check the type of each atom and extract its content
(convert a float atom to a float, or a symbol atom to a symbol).
