6.1.1. About GDB

GDB, the GNU Project debugger, allows 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 has happened, when your program has stopped.

 Change things in your program, so you can experiment with

correcting the effects of one bug and go on to learn about

another.
