C-Library function wrapper for use with DDK?

Anyone happen to have a nice collection of C-Library function wrappers for use with the Windows DDK? I am aware of those that exist in libcntpr.lib, but it is limited to string manipulation and does not contain such functions as the following:

(f)read, (f)write, (f)open, (f)close, malloc, free and fstat

Anyone with pointers to some source would be greatly appreciated.
