@subsection Starting GUD
There are several commands for starting a debugger under GUD, each
corresponding to a particular debugger program.
@table @kbd
@item M-x gdb @key{RET} @var{file} @key{RET}
@findex gdb
Run GDB as a subprocess of Emacs. This uses an IDE-like graphical
interface; see @ref{GDB Graphical Interface}. Only GDB works with the
graphical interface.
@item M-x gud-gdb @key{RET} @var{file} @key{RET}
@findex gud-gdb
Run GDB as a subprocess of Emacs. This command creates a buffer for
input and output to GDB, and switches to it. If a GDB buffer already
exists, it just switches to that buffer. (To run GDB in an IDE-like
graphical interface instead, see @ref{GDB Graphical Interface}.)
exists, it just switches to that buffer.
@item M-x dbx @key{RET} @var{file} @key{RET}
@findex dbx
Run DBX as a subprocess of Emacs.
Run DBX as a subprocess of Emacs. Since Emacs does not implement a
graphical interface for DBX, communication with DBX works by typing
commands in the GUD interaction buffer. The same is true for all
the other supported debuggers.
