I'm wrote a function to resize a buffer, but I'm not sure what the

b_outputbytes member is for, and therefor don't know wether I should care

about it or not. It is set to 2 by default I noticed. Since b_samples is a

float* I wonder why this is not 4, and what "output" it is referring to. I

guess it has to do with b_outputfmt... but what's that?

Below is my code. It seems to work fine btw, in case someone's interested.

I also tried to use the sysmem api but that didn't seem to be compatible. Is

the buffer relying on legacy code for its memory allocation, or is there a

int mutResizeBuffer(t_buffer *b, long nFrames, long nChans)

t_resizebytes((char *)b->b_samples, b->b_size * sizeof(float),

// t_freebytes((char *)b->b_samples, b->b_size * sizeof(float));

// b->b_samples = (float *)t_getbytes(newSize * sizeof(float));

//b->b_outputbytes = sizeof(float); // for if we weren't already dealing

good reason why its not using sysmem_* ?

{
    if(!b->b_valid)
        return 1;

    long saveinuse = b->b_inuse;
    b->b_inuse = true;

    t_resizebytes((char *)b->b_samples, b->b_size * sizeof(float),
                    newSize * sizeof(float));

    // alternative for resizebytes
    // t_freebytes((char *)b->b_samples, b->b_size * sizeof(float));
    // b->b_samples = (float *)t_getbytes(newSize * sizeof(float));

    // update buffer attributes
    b->b_size = newSize; // size in samples
    b->b_nchans = nChans;
    b->b_frames = nFrames;
    //b->b_outputbytes = sizeof(float); // for if we weren't already dealing
with floats?
