commit

Commit data.length samples pointed to by data to the ringbuffer this.

data.length and out_samples define the rate conversion to perform on the samples in data. For negative rates, out_samples must be negative and data.length positive.

When out_samples is positive, the first sample will be written at position sample in the ringbuffer. When out_samples is negative, the last sample will be written to sample in reverse order.

out_samples does not need to be a multiple of the segment size of the ringbuffer although it is recommended for optimal performance.

accum will hold a temporary accumulator used in rate conversion and should be set to 0 when this function is first called. In case the commit operation is interrupted, one can resume the processing by passing the previously returned accum value back to this function.

MT safe.

Parameters:

this	the RingBuffer to commit
sample	the sample position of the data
data	the data to commit
out_samples	the number of samples to write to the ringbuffer
accum	accumulator for rate conversion.
in_samples	the number of samples in the data to commit

Returns:

The number of samples written to the ringbuffer or -1 on error. The number of samples written can be less than out_samples when this was interrupted with a flush or stop.
