KSRTAUDIO_SETWRITEPACKET_INFO structure

Description

The KSRTAUDIO_SETWRITEPACKET_INFO structure describes information associated with an audio packet.

Members

`PacketNumber`

The number of the packet written by the OS to the WaveRT buffer. Depending on the values returned by the driver in the KSPROPERTY_RTAUDIO_GETPACKETCOUNT property, the PacketNumber may skip values. For more information, see KSPROPERTY_RTAUDIO_PACKETCOUNT.

`Flags`

Additional attributes related to the packet or stream.

KSSTREAM_HEADER_OPTIONSF_ENDOFSTREAM - This flag indicates that this packet represents the end of the data stream.

`EosPacketLength`

The length of the EOS packet if KSSTREAM_HEADER_OPTIONSF_ENDOFSTREAM is specified in Flags. Zero is a valid value. If KSSTREAM_HEADER_OPTIONSF_ENDOFSTREAM is not specified in Flags, this parameter is ignored. The EosPacketLength is measured in bytes.
