You can interact with -;; GDB through the GUD buffer in the usual way, but there are also further -;; buffers which control the execution and describe the state of your program. -;; It separates the input/output of your program from that of GDB and displays -;; expressions and their current values in their own buffers. It also uses -;; features of Emacs 21 such as the display margin for breakpoints, and the -;; toolbar (see the GDB Graphical Interface section in the Emacs info manual). - -;; Start the debugger with M-x gdba. - -;; This file has evolved from gdba.el from GDB 5.0 written by Tom Lord and Jim -;; Kingdon and uses GDB's annotation interface. You don't need to know about -;; annotations to use this mode as a debugger, but if you are interested -;; developing the mode itself, then see the Annotations section in the GDB -;; info manual.
