Details

This function returns information about the current tradeskill, which is the one currently visible in the Trade Skill frame. If the Trade Skill frame isn't open then 'UNKNOWN' is returned for 'tradeSkillName' and zero for all other values.

Based on use of the function in Blizzard's code, 'tradeSkillName' appears to be a localized name for the tradeskill.
