ACX_STREAMAUDIOENGINE_CONFIG structure (acxelements.h)
The ACX_STREAMAUDIOENGINE_CONFIG structure is used to define the stream audio engine configuration.
Syntax
typedef struct _ACX_STREAMAUDIOENGINE_CONFIG {
ULONG Size;
ULONG Id;
const GUID *Name;
ULONG Flags;
ACXVOLUME VolumeElement;
ACXMUTE MuteElement;
ACXPEAKMETER PeakMeterElement;
PACX_STREAMAUDIOENGINE_CALLBACKS Callbacks;
} ACX_STREAMAUDIOENGINE_CONFIG, *PACX_STREAMAUDIOENGINE_CONFIG;
Members
Size
The length, in bytes, of this structure.
Id
A number that represents the element ID.
Name
A pointer to a GUID that represents the name of the element. Can be used for debugging and will default to GUID_NULL if not provided.
Flags
Acx peakmeter configuration flags defined by the ACX_STREAMAUDIOENGINE_CONFIG_FLAGS enum.
No flag bits are currently defined. Set this member to zero - AcxStreamAudioEngineConfigNoFlags.
VolumeElement
An existing ACXVOLUME object that is used for volume operations by the stream audio engine.
MuteElement
An existing ACXMUTE object that is used for mute operations by the stream audio engine.
PeakMeterElement
An existing ACXPEAKMETER object that is used for peakmeter operations by the stream audio engine.
Callbacks
The ACX_STREAMAUDIOENGINE_CALLBACKS structure that identifies the driver callbacks for ACX audio engine streaming operations.
Remarks
Example
Example usage is shown below.
ACX_STREAMAUDIOENGINE_CONFIG audioEngineCfg;
ACX_STREAMAUDIOENGINE_CONFIG_INIT(&audioEngineCfg);
audioEngineCfg.VolumeElement = volumeElement;
audioEngineCfg.MuteElement = muteElement;
audioEngineCfg.PeakMeterElement = peakmeterElement;
audioEngineCfg.Callbacks = &streamAudioEngineCallbacks;
