API LFGGetDungeonInfoByID()

Returns data about a particular instance.

Usage
LFGGetDungeonInfoByID(dungeonID)

Takes

 * InstanceId

Returns

 * a table containing 12 values.

LFG_RETURN_VALUES = { name = 1, typeID = 2, minLevel = 3, maxLevel = 4, recLevel = 5,	--Recommended level minRecLevel = 6,	--Minimum recommended level maxRecLevel = 7,	--Maximum recommended level expansionLevel = 8, groupID = 9, texture = 10, difficulty = 11, maxPlayers = 12, } --(from LFGframe.lua)

For Example, /print (LFGGetDungeonInfoByID(1)) will return data about Wailing caverns. Something like (I guessed at the values)
 * Wailing Caverns
 * 1
 * 15
 * 30
 * 20
 * 40
 * 1
 * 151
 * //texture/file
 * 1
 * 5

If you wanted just the name:

/print LFGGetDungeonInfoByID(1)[LFG_RETURN_VALUES.name] Wailing Caverns
