Enumeration Type Documentation

mpd_replay_gain_mode

enum mpd_replay_gain_mode

MPD's replay gain mode.

Since

libmpdclient 2.19, MPD 0.16.

Enumerator
MPD_REPLAY_OFF	ignore ReplayGain tag values
MPD_REPLAY_TRACK	use per-track ReplayGain values
MPD_REPLAY_ALBUM	use per-album ReplayGain values
MPD_REPLAY_AUTO	use available ReplayGain value; if both track and album tags are available, prefer track values.
MPD_REPLAY_UNKNOWN	Unknown mode

Function Documentation

mpd_parse_replay_gain_name()

enum mpd_replay_gain_mode mpd_parse_replay_gain_name

(

const char *

name

)

Parse a mpd_pair value to check which replay gain mode it contains.

mpd_lookup_replay_gain_mode()

const char * mpd_lookup_replay_gain_mode

(

enum mpd_replay_gain_mode

mode

)

Looks up the name of the specified replay gain mode.

Returns

the name, or NULL if the replay gain mode is not valid

Since

libmpdclient 2.19.

mpd_send_replay_gain_status()

bool mpd_send_replay_gain_status

(

struct mpd_connection *

connection

)

Queries the current state of replay gain mode on MPD.

Sends the "replay_gain_status" command to MPD. Call mpd_recv_replay_gain_status() to read the response.

Parameters

connection

the connection to MPD

Returns

true on success, false on error

Since

MPD 0.16, libmpdclient 2.19.

mpd_recv_replay_gain_status()

enum mpd_replay_gain_mode mpd_recv_replay_gain_status

(

struct mpd_connection *

connection

)

Receives the current state of replay gain mode on MPD. Shortcut for mpd_recv_pair_named() and mpd_parse_replay_gain_name() ad mpd_return_pair().

Parameters

connection

the connection to MPD

Returns

mpd_replay_gain_mode object: MPD_REPLAY_UNKNOWN on error (or unknown ReplayGain mode); other modes on success.

Since

MPD 0.16, libmpdclient 2.21.

mpd_run_replay_gain_status()

enum mpd_replay_gain_mode mpd_run_replay_gain_status

(

struct mpd_connection *

connection

)

Shortcut for mpd_send_replay_gain_status(), mpd_recv_replay_gain_status() and mpd_response_finish().

Parameters

connection

the connection to MPD

Returns

mpd_replay_gain_mode object: MPD_REPLAY_UNKNOWN on error (or unknown ReplayGain mode); other modes on success.

Since

MPD 0.16, libmpdclient 2.19.

mpd_send_replay_gain_mode()

bool mpd_send_replay_gain_mode	(	struct mpd_connection *	connection,
		enum mpd_replay_gain_mode	mode
	)

Sets the current state of replay gain mode on MPD.

Parameters

connection	the connection to MPD
mode	the desired replay gain mode

Returns

true on success, false on error

Since

MPD 0.16, libmpdclient 2.19.

mpd_run_replay_gain_mode()

bool mpd_run_replay_gain_mode	(	struct mpd_connection *	connection,
		enum mpd_replay_gain_mode	mode
	)

Shortcut for mpd_send_replay_gain_mode() and mpd_response_finish().

Parameters

connection	the connection to MPD
mode	mode the desired replay gain mode

Returns

true on success, false on error

Since

MPD 0.16, libmpdclient 2.19.
