MEASURE_END

#define MEASURE_END   (void)clock_gettime(CLOCK_MONOTONIC, &toc);

Stop measurement

MEASURE_INIT

#define MEASURE_INIT

Value:

    struct timespec tic;\
    struct timespec toc;

Initialize time measurement

MEASURE_PRINT

#define MEASURE_PRINT	(		PART,
			X )

Value:

    MYMPD_LOG_DEBUG(PART, "Execution time for %s: %" PRId64 " ms", X, \
    (int64_t)(((toc.tv_sec * 1000) + (toc.tv_nsec / 1000000)) - ((tic.tv_sec * 1000) + (tic.tv_nsec / 1000000))));

(

const char *

filename

)

Gets the extension of a filename

Parameters

pointer to the extension

get_ipv6_support()

bool get_ipv6_support

(

void

)

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

Returns

true on IPv6 support, else false

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
