34.1.2 Port Objects
Port objects, as returned by openport(), have the following methods:
- Close the port.
- Return the file descriptor as an int.
- Return the number of filled samples.
- Return the number of fillable samples.
- 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).
- Write samples into the queue, blocking if necessary. The samples are encoded as described for the readsamps() return value.
- Return the `fill point'.
- Set the `fill point'.
- Return a configuration object containing the current configuration of the port.
- Set the configuration from the argument, a configuration object.
- Get status information on last error.
