Function Documentation

int register_sound_dsp	(	struct file_operations *	fops,
		int	dev
	)

Register a DSP Device.

Parameters:

	fops	interface
	dev	unit number

Returns:

allocated number or negative error value

This function allocates both the audio and dsp device entries together and will always allocate them as a matching pair - eg dsp3/audio3 (Linux)

Definition at line 175 of file soundcore.c.

int register_sound_midi	(	struct file_operations *	fops,
		int	dev
	)

Register a MIDI Device.

Parameters:

	fops	interface
	dev	unit number

Returns:

allocated number or negative error value

Definition at line 231 of file soundcore.c.

int register_sound_mixer	(	struct file_operations *	fops,
		int	dev
	)

Register a Mixer Device.

Parameters:

	fops	interface
	dev	unit number

Returns:

allocated number or negative error value

Unit number has to be -1 for find first free or we panic.

Definition at line 204 of file soundcore.c.

int register_sound_special	(	struct file_operations *	fops,
		int	unit
	)

Register a Special Sound Node.

Parameters:

	fops	interface
	unit	unit number

Returns:

allocated number or negative error value

For now no special nodes are supported. Only OSS/Free (old ISA) and dmasound use this feature.

Definition at line 264 of file soundcore.c.

int register_sound_synth	(	struct file_operations *	fops,
		int	dev
	)

Register a synth Device.

Parameters:

	fops	interface
	dev	unit number

Returns:

allocated number or negative error value

For now no raw synthesizer nodes are supported. Only wavefront.c uses this feature.

Definition at line 336 of file soundcore.c.

struct file_operations* soundcore_req_fops	(	int	type,
		int	num
	)			[read]

Query for device operations structure.

Parameters:

	type	desired device type
	num	desired device number

Returns:

fops pointer; NULL on error
