[PD-dev] Sending list of floats out an outlet

[Krzysztof Czaja]

hi Ben,

if 'x' is your object pointer, 'n' is the number of floats, and
you already store them in an array of atoms 'a', then the call
will be

outlet_list(x, &s_list, n, a);

If the floats are kept in a float* array, then you need to
allocate an array of atoms, and copy the floats into it, using
SETFLOAT macro in a loop.

The tricky part could be deciding, how to allocate this output
array -- this was discussed some time ago on pd-dev.  Also, there
are several examples in zexy, ggee, cyclone, etc.
