Vaugely Correct.

"Don't bother".
Xlib is a large and complicated beast. Unless you have a lot of time
free, or are insanely brave, I suggest that you avoid dealing with it
directly.
Its source-code is a standard part of the X11R6 source distribution,
and hence can be found in the XFree86 Source Code. Its exact location
in that tree is left as an exercise to the reader.
If your desire to learn how to program using Xlib, you should refer to
souce code from simple X11 programs, the X11 programming manuals, and
to any XLib tutorial material you can find. (There is a book about
XLib and Motif programming by Jan Newmarch which I learnt the basics
of XLib programming from)
