AVCSTRM_FUNCTION enumeration (avcstrm.h)

The AVCSTRM_FUNCTION enumeration defines the functionality exposed by the avcstrm.sys driver.

Syntax

typedef enum _AVCSTRM_FUNCTION {
  AVCSTRM_READ,
  AVCSTRM_WRITE,
  AVCSTRM_ABORT_STREAMING,
  AVCSTRM_OPEN,
  AVCSTRM_CLOSE,
  AVCSTRM_GET_STATE,
  AVCSTRM_SET_STATE,
  AVCSTRM_GET_PROPERTY,
  AVCSTRM_SET_PROPERTY
} AVCSTRM_FUNCTION;

Constants

AVCSTRM_READ Read data from a stream.
AVCSTRM_WRITE Write data to a stream.
AVCSTRM_ABORT_STREAMING Abort streaming. This cancels all streaming IRPs. To cancel an individual IRP, use IoCancelIrp.
AVCSTRM_OPEN Open a stream in a specific format.
AVCSTRM_CLOSE Close a stream and free any resources allocated for the stream.
AVCSTRM_GET_STATE Obtain the stream state.
AVCSTRM_SET_STATE Place the stream into a new state.
AVCSTRM_GET_PROPERTY Get stream property. This function is not implemented.
AVCSTRM_SET_PROPERTY Set stream property. This function is not implemented.
