Function Documentation

◆ mpd_message_begin()

struct mpd_message * mpd_message_begin ( const struct mpd_pair pair)

Begins parsing a new message.

Parameters
pairthe 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")
Since
libmpdclient 2.5

◆ mpd_message_feed()

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
Since
libmpdclient 2.5

◆ mpd_message_free()

void mpd_message_free ( struct mpd_message message)

Frees a mpd_message object.

Since
libmpdclient 2.5

◆ mpd_message_get_channel()

const char * mpd_message_get_channel ( const struct mpd_message message)

Returns the channel name.

Since
libmpdclient 2.5

◆ mpd_message_get_text()

const char * mpd_message_get_text ( const struct mpd_message message)

Returns the message text.

Since

◆ mpd_run_subscribe()

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

Shortcut for mpd_send_subscribe() and mpd_response_finish().

Parameters

true on success
Since
libmpdclient 2.5

◆ mpd_send_unsubscribe()

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

const char *  channel 
)

Shortcut for mpd_send_unsubscribe() and mpd_response_finish().

Parameters
connectionthe connection to MPD
channelthe channel name
Returns
true on success
Since

◆ mpd_send_send_message()

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
connectionthe connection to MPD
channelthe channel name
textthe message text
Returns
true on success
Since

◆ mpd_run_send_message()

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
connectionthe connection to MPD
channelthe channel name
textthe message text
Returns
true on success
Since
libmpdclient 2.5

◆ mpd_send_read_messages()

bool mpd_send_read_messages ( struct mpd_connection connection)

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

Parameters
connectionthe connection to MPD
Returns
true on success
Since
libmpdclient 2.5

◆ mpd_recv_message()

struct mpd_message * mpd_recv_message ( struct mpd_connection connection)

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
Since
libmpdclient 2.5

◆ mpd_send_channels()

bool mpd_send_channels ( struct mpd_connection connection)
