Debugging With Gdb: The Gnu Source-Level Debugger Fifth Edition, for Gdb Version, April 1998

Debugging with GDB details the GNU GDB debugging utility. The purpose of a debugger such as GDB is to allow you to see what is going on "inside" another program while it executes--or what another program was doing at the moment it crashed. GDB can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act: * Start your program, specifying anything that might affect its behavior. * Make your program stop on specified conditions. * Examine what happened when your program stopped. * Change things in your program so you can experiment with correcting the effects of one bug and go on to learn about another. You can use GDB to debug programs written in C or C++. This book is a printed version of the GDB documentation, available online from the Free Software Foundation.
