20.1.2 Port Objects

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.

`setconfig`(config)
  Set the configuration from the argument, a configuration object.

`getstatus`(list)
  Get status information on last error.
