playlist	name of the playlist to check

Returns

true if it is a smart playlist else false

smartpls_get_mtime()

time_t smartpls_get_mtime	(	sds	workdir,
		const char *	playlist
	)

Returns the smart playlist last modification time

Parameters

workdir	myMPD working directory
playlist	name of the playlist to check

Returns

last modification time

smartpls_save()

static bool smartpls_save ( sds  workdir, const char *  smartpltype, const char *  playlist, const char *  fields, const char *  sort, bool  sortdesc, int  max_entries  )

static
