There are MANY function calls inside even the most basic low-level 
libraries for which no documentation exists.
For example, in user32.dll is the function RegisterUserAPIHooks. That is 
totally undocumented.

That is just one example.
However, it is one of the many undocumented functions that only exist to 
allow components of windows to talk to each other (in this case it exists 
only to allow uxtheme/comctl32 to hook user32 and do non-client-area themeing).
The question is, do we implement such functions?
