Port objects, as returned by openport(), have the following methods:
- closeport()
- Close the port.
- getfd()
- Return the file descriptor as an int.
- getfilled()
- Return the number of filled samples.
- getfillable()
- Return the number of fillable samples.
- readsamps(nsamples)
- Read a number of samples from the queue, blocking if necessary. Return the data as a string containing the raw data, (e.g., 2 bytes per sample in big-endian byte order (high byte, low byte) if you have set the sample width to 2 bytes).
- writesamps(samples)
- Write samples into the queue, blocking if necessary. The samples are encoded as described for the readsamps() return value.
- getfillpoint()
- Return the `fill point'.
- setfillpoint(fillpoint)
- Set the `fill point'.
- getconfig()
- Return a configuration object containing the current configuration of the port.
