get_extension_from_filename()

const char * get_extension_from_filename

(

const char *

filename

)

Gets the extension of a filename

Parameters

filename

filename to get extension from

Returns

pointer to the extension

get_ipv6_support()

bool get_ipv6_support

(

)

Checks for IPv6 support by searching for an IPv6 address on all interfaces

Returns

true on IPv6 support, else false

get_local_ip()

sds get_local_ip ( void )

static

Gets the ip address of the first interface

Returns

ip address as sds string

get_mympd_host()

static

Private definitions

Private functions Gets the listening address of the embedded webserver

Parameters

mpd_host	mpd_host config setting
http_host	http_host config setting

Returns

address of the embedded webserver as sds string

is_streamuri()

bool is_streamuri

(

const char *

uri

)

Checks if uri is a remote uri or a local file

Parameters

uri	uri to check

Returns

true it is a uri else false

is_virtual_cuedir()

bool is_virtual_cuedir	(	sds	music_directory,
		sds	filename )

Checks if the filename is a mpd virtual cue sheet directory MPD uses the cue filename as path, we simply check if the filename is a file or not

		struct t_config *	config,
		bool	prefer_ssl )

Resolves mympd:// uris to the real myMPD host address and respects the mympd_uri config option

Parameters

uri	uri to resolv
mpd_host	mpd host
config	pointer to config struct
prefer_ssl	Prefer https over http

Returns

resolved uri
