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 and the channel is not currently enabled. The device needs to be stopped before enabling the channel.
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. Enabled channels can be reconfigured after the device has been started, but other channels cannot be enabled without stopping the device first unless the BASS_ASIO_ALLINPUTS and/or BASS_ASIO_ALLOUTPUTS flags were set with BASS_ASIO_Init.

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

Example

Enable output channel 0.
