DevLib — Homebrew library of C/C++ utilities,
drivers, and algorithms. I've contributed much of the code
directly and supervised the development and integration of
the rest of it. See DevLib .
POSIX — I always write my programs with portability in mind,
and the POSIX API is usually my API of choice for UNIX, Linux
Mac OS X and even some Windows development.
Win32 — Most of the KERNEL32, USER32 and GDI32 APIs, including
overlapped I/O, threading, events, message passing, memory management,
2D drawing and window management.
Boost — A collection of high quality, general-purpose C++
libraries. See: http://www.boost.org/ .
Qt — Currently my favourite GUI framework. I expecially
like the elegant signal/slot concept and its simple memory
management solution. http://www.trolltech.com/
MFC — I've been using these Microsoft ...err... Fine Classes,
including DAO and ATL, for much longer than one would like
to admit. It's a miracle I've even managed to retain some sanity.
