Debugging is the art of finding mistakes in code. Using a debugger, programmers can trace program execution line by line, inspect variables, and see what the program is doing at any given time. The Art of Debugging with GDB and DDD will help programmers master the art of debugging with two popular Open Source debuggers: GDB and DDD. It also discusses other tools that help prevent, catch, and fix bugs in programs. The book integrates general debugging principles with concrete examples and covers many topics other debugging books leave out, such as segmentation faults, threaded programming, and distributed/parallel programming.
