Namespace: Un4seen.Bass.AddOn.Mix
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.17.5
Syntax
[DllImportAttribute("bassmix")] public static BASSActive BASS_Mixer_ChannelIsActive( int handle )
Parameters
- handle
- Type: SystemInt32
The handle of the mixer source channel to check (which was add via BASS_Mixer_StreamAddChannel(Int32, Int32, BASSFlag) or BASS_Mixer_StreamAddChannel(Int32, Int32, BASSFlag) or BASS_Mixer_StreamAddChannelEx(Int32, Int32, BASSFlag, Int64, Int64)) beforehand).
Return Value
Type: BASSActiveThe return value is one of the folowing (see BASSActive):
| BASS_ACTIVE_STOPPED | The source is not active, or handle is not a valid mixer source channel. |
| BASS_ACTIVE_PLAYING | The source is playing. |
| BASS_ACTIVE_PAUSED | The source is paused. |
| BASS_ACTIVE_STALLED | The source is paused. |
| BASS_ACTIVE_WAITING | The channel is waiting to start because it was delayed by BASS_Mixer_StreamAddChannelEx(Int32, Int32, BASSFlag, Int64, Int64). |
| BASS_ACTIVE_QUEUED | The channel is waiting in a queue. |
Remarks
This function gives the status of a source channel as the mixer currently sees it, which may be ahead of what is heard if the mixer is playing due to buffering. The source channel's status is unaffected by the mixer's status, eg. whether it is playing or stopped.
A BASS_SYNC_STALL sync can be set via BASS_Mixer_ChannelSetSync(Int32, BASSSync, Int64, SYNCPROC, IntPtr) to be notified when a channel stalls/resumes.
| ERROR CODE | Description |
|---|---|
| BASS_ERROR_HANDLE | The channel is not plugged into a mixer. |
