How to write?

Hi there,

I'm running a fork of your bindings with this code:

import sfi
import os

var frames = 34
var sndfile: ptr TSNDFILE
var info: TINFO
info.channels = 1
info.frames = int64(frames)
info.samplerate = cint(44100)
info.format = cint(65542)
info.seekable = cint(1)
info.sections = cint(1)


sndfile = sfi.open(
    paramStr(1).expandTilde(), 
    sfi.WRITE,
    cast[ptr TINFO](info.addr)
    )

var samples = cast[ptr UncheckedArray[cfloat]](alloc0(sizeof(cfloat) * frames))

for i in 0..frames-1:
  samples[i] = cfloat(i)

echo format_check(cast[ptr TINFO](info.addr))

var num_items = cast[int64](info.channels * info.frames)

echo sfi.writef_float(sndfile, samples[0].addr, num_items)

discard sfi.close(sndfile)
dealloc(samples)

but it always returns 0 items written.

In my bindings I simply added the write functions which are almost identical to the read functions.

Any ideas on how I can make this work because right now it doesn't crash but the file is always empty after the program is complete.

Continued development

First of all, thanks for this small wrapper. I noticed that the PR for writing files #7 has not been merged, or any other activity for that matter, in over a year. Currently, I'm using the PR without issues, but it would be great if I could just install it via nimble. Will there be any further updates?

@jamesb93: If there is no more development here, would you be okay if someone changed the URL in the nimble directory to your fork? Are you still using this? Or should I fork your fork, in case people want support?
