IAudioProcessingObjectRT::APOProcess method (audioenginebaseapo.h)
The APOProcess method causes the APO to make a processing pass.
Syntax
void APOProcess(
[in] UINT32 u32NumInputConnections,
[in] APO_CONNECTION_PROPERTY **ppInputConnections,
[in] UINT32 u32NumOutputConnections,
[in, out] APO_CONNECTION_PROPERTY **ppOutputConnections
);
Parameters
[in] u32NumInputConnections
The number of input connections that are attached to this APO.
[in] ppInputConnections
An array of input connection property structures. There is one structure per input connection.
[in] u32NumOutputConnections
The number of output connections that are attached to this APO.
[in, out] ppOutputConnections
An array of output connection property structures. There is one structure per output connection.
Return value

| Return code | Description |
|---|
Remarks
The APOProcess method must not change the data in the ppOutputConnections array. But it must set the properties of the output connections after processing.
The APOProcess method is called from a real-time processing thread. The implementation of this method must not touch paged memory and it should not call any system blocking routines.
For a detailed look at an implementation of this method, see the Swap sample code and refer to the Swapapolfx.cpp file.
