AuSoundRecord(3) Library Functions Manual AuSoundRecord(3) Name AuSoundRecord - create a flow to record audio to any destination. Synopsis #include <audio/audiolib.h> #include <audio/soundlib.h> AuEventHandlerRec *AuSoundRecord(server, source, gain, num_samples, mode, sound_data, flow, volume_mult_elem, status) AuServer *server; AuDeviceID source; AuFixedPoint gain; AuUint32 num_samples; int mode; AuSoundDataPtr sound_data; AuFlowID *flow; /* RETURN */ int *volume_mult_elem; /* RETURN */ AuStatus *status; /* RETURN */ Arguments server Specifies the connection to the audio server. source Specifies the input device to use. gain Specifies the gain for the input device. num_samples Specifies the number of samples to record. mode Specifies the line mode for the input device. Currently the following line modes are defined: AuDeviceInputModeNone, AuDeviceIn- putModeLineIn, AuDeviceInputModeMicrophone. sound_data Specifies the sound information. 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 AuSoundRecord creates a flow to record audio from source to any destination and returns a pointer to the event handler created or NULL if there was an error. The sound_data structure contains the necessary information about the audio format and the data handling function. Errors AuBadDevice.
