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. References DEBUG_MSG, dsp, and sound_insert_unit().

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. References DEBUG_MSG, and sound_insert_unit().

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. References DEBUG_MSG, and sound_insert_unit().

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. References DEBUG_MSG.

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. References DEBUG_MSG.

struct file_operations* soundcore_req_fops (  int  type, int  num )

Query for device operations structure. Parameters: type  desired device type num  desired device number Returns: fops pointer; NULL on error Definition at line 427 of file soundcore.c. References __look_for_unit(), and dsp. Referenced by snd_open_dev().

void unregister_sound_dsp (  int  unit  )

Unregister a DSP Device. Parameters: unit  unit number Definition at line 349 of file soundcore.c. References DEBUG_MSG, dsp, and sound_remove_unit().

void unregister_sound_midi (  int  unit  )

Unregister a MIDI Device. Parameters: unit  unit number Definition at line 377 of file soundcore.c. References DEBUG_MSG, and sound_remove_unit().

void unregister_sound_mixer (  int  unit  )

Unregister a Mixer Device. Parameters: unit  unit number Definition at line 363 of file soundcore.c. References DEBUG_MSG, and sound_remove_unit().

void unregister_sound_special (  int  unit  )

Unregister a Special Node. Parameters: unit  unit number For now no special nodes are supported. Only OSS/Free (old ISA) and dmasound use this feature. Definition at line 396 of file soundcore.c. References DEBUG_MSG.

void unregister_sound_synth (  int  unit  )

Unregister a synth Device. Parameters: unit  unit number For now no raw synthesizer nodes are supported. Only wavefront.c uses this feature. Definition at line 411 of file soundcore.c. References DEBUG_MSG.
