Arguments
server Specifies the connection to the audio server.

filename Specifies the name of the file to record to.

source Specifies the input device to record from.

gain Specifies the gain for the input device.

num_samples
Specifies the number of samples to record. Use AuUnlimitedSamples to record an unlimited number of samples.

callback Specifies the procedure to be called for additional event processing.

LinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB, and AuFormatLinearUn-
signed16LSB.

flow If non-NULL, returns the flow ID.

volume_mult_elem
Accord to the comment in the source, not implemented.

status If non-NULL, flush the output buffer and return the status from the server.

Description
