[Csnd-dev] CPOF - Array of ftables

Hi again :)

I'm trying to design an opcode that accepts an array of ftables, access 
these tables individually, and iterate over them. But it seems that I 
can't use FTFind().

My code looks like this:

csnd::Vector<MYFLT> &arr = inargs.vector_data<MYFLT>(1);
FUNC *ftp = csound->FTFind(csound, &arr[0]);

And the error I get is:

error: 'FTFind' is a private member of 'CSOUND_'

What would be the correct way to achieve that? Sorry if this is a dumb 
question, I'm just starting looking into plugin development, and I'm 
unsure about the best practices.
