For a tutorial introduction to the Xlib C API and concepts, Adrian
Nye's O'Reilly Book, Volume 1 : Xlib Programming Manual is still
probably the best source.
You can download the source code examples from the O'Reilly
website: http://www.oreilly.com/catalog/v1/index.html
Postscript versions of the various specs are here:
ftp://ftp.x.org/pub/R6.6/xc/doc/hardcopy/
(can be read with the gv program or printed directly).
Be sure to install the X11 development man pages on your
machine.
Kenton Lee has a lot of good links:
http://www.rahul.net/kenton/xsites.html
including some tutorials.
Here is a nice book on using the most common
Linux C/C++ compiler that you can buy or download
in pdf form:
http://www.network-theory.co.uk/gcc/intro/
Three other tools that you will want to be acquainted
with are gdb, a source level debugger, gprof, a
profiler, and valgrind, a tool for detecting memory
access violations and leaks (somewhat similar to
Rational's Purify product).
