BASS.NET API for the Un4seen BASS Audio LibraryBassCdBASS_CD_StreamSetTrack Method BASS.NET API for the Un4seen BASS Audio Library
Changes the track of a CD stream.

Namespace: Un4seen.Bass.AddOn.Cd
Assembly: Bass.Net (in Bass.Net.dll) Version:

[DllImportAttribute("basscd.dll", CharSet = CharSet.Auto)]
public static bool BASS_CD_StreamSetTrack(
	int handle,
	int track


Type: SystemInt32
The CD stream handle.
Type: SystemInt32
The new track... 0 = the first track, BASS_CD_TRACK_PREGAP = 1st track pregap (not all drives support reading of the 1st track pregap).

Return Value

Type: Boolean
If successful, is returned, else is returned. Use BASS_ErrorGetCode to get the error code.

The stream's current position is set to the start of the new track.

This function is identical to using the BASS_POS_CD_TRACK 'mode' with BASS_ChannelSetPosition(Int32, Int64, BASSMode). Either can be used with a BASS_SYNC_END sync (set via BASS_ChannelSetSync(Int32, BASSSync, Int64, SYNCPROC, IntPtr)) to play one track after another.

ERROR CODEDescription
BASS_ERROR_HANDLEhandle is not valid.
BASS_ERROR_NOCDThere's no CD in the drive.
BASS_ERROR_CDTRACKtrack is invalid.
BASS_ERROR_NOTAUDIOThe track is not an audio track.


Play an entire CD without any gap between tracks:
