Typedef Documentation

This struct is used by cdio_audio_get_volume and cdio_audio_set_volume

This struct is used by the cdio_audio_read_subchannel

This struct is used by the CDROMPLAYTRKIND ioctl

Function Documentation

uint32_t cdio_audio_get_msf_seconds ( msf_t p_msf)

Return the number of seconds (discarding frame portion) of an MSF

driver_return_code_t cdio_audio_get_volume ( CdIo_t p_cdio,
cdio_audio_volume_t p_volume 
)

Get volume of an audio CD.

Parameters
p_cdiothe CD object to be acted upon.
p_volumeplace to put the list of volume outputs levels

p_volume can be NULL in which case we return only whether the driver has the ability to get the volume or not.

driver_return_code_t cdio_audio_pause ( CdIo_t p_cdio)

Pause playing CD through analog output

Parameters
p_cdiothe CD object to be acted upon.
driver_return_code_t cdio_audio_play_msf ( CdIo_t p_cdio,
msf_t p_start_msf,
msf_t p_end_msf 
)

Playing CD through analog output at the given MSF.

Parameters
p_cdiothe CD object to be acted upon.
p_start_msfpointer to staring MSF
p_end_msfpointer to ending MSF
driver_return_code_t cdio_audio_play_track_index ( CdIo_t p_cdio,
cdio_track_index_t p_track_index 
)

Playing CD through analog output at the desired track and index

Parameters
p_cdiothe CD object to be acted upon.
p_track_indexlocation to start/end.
driver_return_code_t cdio_audio_read_subchannel ( CdIo_t p_cdio,
cdio_subchannel_t p_subchannel 
)

Get subchannel information.

Parameters
p_cdiothe CD object to be acted upon.
p_subchannelplace for returned subchannel information
driver_return_code_t cdio_audio_resume ( CdIo_t p_cdio)

Resume playing an audio CD.

Parameters
p_cdiothe CD object to be acted upon.
driver_return_code_t cdio_audio_set_volume ( CdIo_t p_cdio,
cdio_audio_volume_t p_volume 
)

Set volume of an audio CD.

Parameters
p_cdiothe CD object to be acted upon.
p_volumeplace for returned volume-level information
driver_return_code_t cdio_audio_stop ( CdIo_t p_cdio)

Stop playing an audio CD.

Parameters
p_cdiothe CD object to be acted upon.
