#Undefned Error trying to compile

you'll see that none of the functions you attempted to use are listed here; it's really no more complicated than the package not implementing them
if you want to use them, you'll need to use a third-party package that does (i'm not necessarily saying there is one, just suggesting that there might be) or do the metaphorical GetProcAddress (most easily using LazyDLL and LazyProc) and call them yourself
