need to call non exported functions of DLL

Question

Hello,

I need to call(get) non exported functions of DLL. Unlike PE export table, non exports do not have any table having entries for these. More over all disassembler like IDAPro and other debuggers only show exported function names with decorated names(After Shift+F3 incase of IDA) and show all other functions like sub_000FF sorts of.

Any idea how to get and call non exported functions of DLL programtically(GetProcAddress after LoadLibrary only calls decorated exported functions not designed for non exports)
