BASS_ASIO_ChannelEnable

Enables/disables processing of a channel.

BOOL BASS_ASIO_ChannelEnable(
    BOOL input,
    DWORD channel,
    ASIOPROC *proc,
    void *user
);

Parameters

input	Dealing with an input channel? FALSE = an output channel.
channel	The input/output channel number... 0 = first.
proc	The user defined function to process the channel... NULL = disable the channel.
user	User instance data to pass to the callback function.

Return value

If successful, then TRUE is returned, else FALSE is returned. Use BASS_ASIO_ErrorGetCode to get the error code.

Error codes

BASS_ERROR_INIT	BASS_ASIO_Init has not been successfully called.
BASS_ERROR_START	The device has been started - it needs to be stopped before (dis)enabling channels.
BASS_ERROR_ILLPARAM	The input and channel combination is invalid.

Remarks

All ASIO channels are mono. Stereo (and above) channels can be formed by joining multiple channels together using BASS_ASIO_ChannelJoin.

Use BASS_ASIO_Start to begin processing the enabled channels. A channel's proc and user parameters can be changed after the device has been started, but the channel cannot be disabled (proc=NULL) without stopping the device first.

BASS channels can be used directly, without needing an ASIOPROC callback function, via BASS_ASIO_ChannelEnableBASS.

Example

Enable output channel 0.
