Function Documentation

mpd_parse_fingerprint_type()

enum mpd_fingerprint_type mpd_parse_fingerprint_type

(

const char *

name

)

Parse a mpd_pair name to check which fingerprint type it contains.

mpd_send_getfingerprint()

bool mpd_send_getfingerprint	(	struct mpd_connection *	connection,
		const char *	uri
	)

Sends the "getfingerprint" command to MPD. Call mpd_recv_pair() to read response lines. Use mpd_parse_fingerprint_type() to check each pair's name; the pair's value then contains the actual fingerprint.

Parameters

connection	a valid and connected mpd_connection
uri	the song URI

Returns

true on success

Since

libmpdclient 2.17, MPD 0.22

mpd_run_getfingerprint_chromaprint()

const char * mpd_run_getfingerprint_chromaprint	(	struct mpd_connection *	connection,
		const char *	uri,
		char *	buffer,
		size_t	buffer_size
	)

Shortcut for mpd_send_getfingerprint(), mpd_recv_pair_named() and mpd_response_finish().

Parameters

connection	a valid and connected mpd_connection
uri	the song URI
buffer	a buffer for the fingerprint string
buffer_size	the size of the buffer (with enough room for a trailing null byte); if the buffer is too small, behavior is undefined; the library may truncate the string or fail

Returns

a pointer to the buffer on success or NULL on error (or if there was no chromaprint in MPD's response)

Since

libmpdclient 2.17, MPD 0.22
