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.
