Members
type The event type. MonitorNotify events are type AuEventTypeMonitorNotify.
serial The serial ID of the event expanded from the 16 bit value sent by the server.
send_event
AuTrue if the event came from a SendEvent protocol request.
server The connection to the audio server that the event was read from.
time The server time in milliseconds when the event was generated.
flow Specifies the ID of the flow that caused the event.
element_num
The index of the ExportMonitor element that gnerated this event.
format The format of the monitor data. Currently, the following formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8, AuFormat-
LinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB, and AuFormatLinearUn-
signed16LSB. Taken from the ExportMonitor element.
num_tracks
The number of tracks in the monitor data. Taken from the ExportMonitor element.
count Always 0.
num_fields
Always 2.
data Monitor data.
data1 Monitor data.
data2 Monitor data.
Description
MonitorNotify events will be sent to clients with flows containing ExportMonitor elements.

AuMakeElementImportClient - initialize an ImportClient element
Synopsis
#include <audio/audiolib.h>
AuMakeElementImportClient(element, sample_rate, format, num_tracks, discard, max_samples, low_water_mark, num_actions, actions)
AuElement *element; /* RETURN */
unsigned short sample_rate;
unsigned char format;
unsigned char num_tracks;
unsigned char discard;
AuUint32 max_samples;
AuUint32 low_water_mark;
int num_actions;
AuElementAction *actions;
Arguments
element Returns the initialized element.
sample_rate
Specifies the sample rate of the audio data.
format Specifies the format of the audio data. Currently, the following formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8,
AuFormatLinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB, and AuFormatLinearUn-
signed16LSB.
num_tracks
Specifies the number of tracks in the audio data.
discard Specifies if the import should be paused initally. Normally AuTrue. AuFalse may crash the server.
max_samples
Specifies the maximum number of samples to accept in a single read. Ignored for "trivial" flows.
low_water_mark
Specifies when to request additional audio data from the client application. When this number of samples are left in the buffer,
and an EOF hasn't been received, a NotifyEvent with kind set to AuElementNotifyKindLowWater will be sent to the client applica-
tion.
num_actions
Specifies the number of actions in actions.
actions Specifies the list of actions to associate with this element. Entries in this list can be initialized with AuMakeChangeStateAc-
tion, AuMakeSendNotifyAction, and AuMakeNoopAction. May be NULL.
Description
AuMakeElementImportClient sets the type of element to AuElementTypeImportClient and initializes the importclient member of element with the
remaining arguments.
AuMakeElementImportClient is implemented as a macro.
