+//! Hacking together the definitions for VxWorks Bindings
+use dox::mem; /*TODO: Figure out what this even does */
+use core::ptr::null;
+use core::ptr::null_mut;
+use core::mem::size_of;
+
+//  Notes: 
+//  We might need to define c_int and c_uint, let's figure that out on the fly 
+//  We should really make sense of the scope resolution, because we currently are looking pretty dumb ...
+//  Glob_T is not needed (?)
+//  This is still massively incomplete, probably not enough to compile std
+//
+//  Currently, we assume _WRS_KERNEL is not defined in the C-libraries.
+//  (they are only defined for kernel-side builds only, and we are building for rtps currently)
+//  In case someone tries to compile for kernel, I've added kernel specific structures and functions
+//  using cfg. To enable them, compile with the feature _WRS_KERNEL on.
+//  (This will also make sure that user-side definitions don't compile as well, at least for
+//  most of them anyway)
+//
+//  The type defs can be different between different compilers and architecture.
+//  An easy way to check the exact types of a faulting type / structure is to 
+//  use gdb on the compiled executable, and use ptype {faulting type} for a
+//  faulting type and ptype struct {struct name} for a faulting structure.
+//  If it shows "No symbol {type / struct name}", that just means that it 
+//  doesn't get called anywhere in the executable, hence it hasn't been
+//  included during the linking process.
+//
+//  !IMPORTANT:
+//  Another tip in finding the type definitions is to use the search
+//	functionality in workspace (flashlight icon in the toolbar).
+//	You can search for all USER definitions by setting the 'Look in:'
+//	parameter to your VSB's usr folder, and the 'File types:' parameter
+//	to *.h.
+//
+//	There are some types that were omitted to be defined, but rather
+//	it was replaced with the type it is defined as in C.
+//	For example, STATUS is all set to c_int, pid_t is all set to c_int.
+//	(I'm not too sure why this was done, but it seems to have been the way
+//	it was done by the previous co-op, so kept it for now.)
