Function Documentation

mpd_malloc struct mpd_message* mpd_message_begin

(

const struct mpd_pair *

pair

)

[read]

Begins parsing a new message.

Parameters:

pair	the first pair in this message (name must be "channel")

Returns:

the new mpd_entity object, or NULL on error (out of memory, or pair name is not "channel")

bool mpd_message_feed	(	struct mpd_message *	output,
		const struct mpd_pair *	pair
	)

Parses the pair, adding its information to the specified mpd_message object.

Returns:

true if the pair was parsed and added to the message (or if the pair was not understood and ignored), false if this pair is the beginning of the next message

void mpd_message_free

(

struct mpd_message *

message

)

Frees a mpd_message object.

mpd_pure const char* mpd_message_get_channel

(

const struct mpd_message *

message

)

Returns the channel name.

mpd_pure const char* mpd_message_get_text

(

const struct mpd_message *

message

)

Returns the message text.

bool mpd_send_subscribe	(	struct mpd_connection *	connection,
		const char *	channel
	)

Sends the "subscribe" command: subscribe to a message channel.

Parameters:

connection	the connection to MPD
channel	the channel name

Returns:

true on success

bool mpd_run_subscribe	(	struct mpd_connection *	connection,
		const char *	channel
	)

Shortcut for mpd_send_subscribe() and mpd_response_finish().

Parameters:

connection	the connection to MPD
channel	the channel name

Returns:

true on success

bool mpd_send_unsubscribe	(	struct mpd_connection *	connection,
		const char *	channel
	)

Sends the "unsubscribe" command: unsubscribe from a message channel.

Parameters:

connection	the connection to MPD
channel	the channel name

Returns:

true on success

bool mpd_run_unsubscribe	(	struct mpd_connection *	connection,
		const char *	channel
	)

Shortcut for mpd_send_unsubscribe() and mpd_response_finish().

Parameters:

connection	the connection to MPD
channel	the channel name

Returns:

true on success

bool mpd_send_send_message	(	struct mpd_connection *	connection,
		const char *	channel,
		const char *	text
	)

Sends the "sendmessage" command: send a message to a channel.

Parameters:

connection	the connection to MPD
channel	the channel name
text	the message text

Returns:

true on success

bool mpd_run_send_message	(	struct mpd_connection *	connection,
		const char *	channel,
		const char *	text
	)

Shortcut for mpd_send_send_message() and mpd_response_finish().

Parameters:

connection	the connection to MPD
channel	the channel name
text	the message text

Returns:

true on success

bool mpd_send_read_messages

(

struct mpd_connection *

connection

)

Sends the "readmessages" command: send a message to a channel.

Parameters:

connection

the connection to MPD

Returns:

true on success

mpd_malloc struct mpd_message* mpd_recv_message

(

struct mpd_connection *

connection

)

[read]

Reads the next mpd_message from the MPD response. Free the return value with mpd_message_free().

Returns:

a mpd_message object on success, NULL on error or end-of-response

bool mpd_send_channels

(

struct mpd_connection *

connection

)

Sends the "channels" command: get a list of all channels.

Parameters:

connection

the connection to MPD

Returns:

true on success

static mpd_malloc struct mpd_pair* mpd_recv_channel_pair

(

struct mpd_connection *

connection

)

[static, read]

Receives the next channel name. Call this in a loop after mpd_send_channels().

Free the return value with mpd_return_pair().

Parameters:

connection

a mpd_connection

Returns:

a "channel" pair, or NULL on error or if the end of the response is reached
