"Major mode for interacting with an inferior debugger process.
The following commands are available:
You start it up with one of the commands M-x gdb, M-x sdb, or
M-x dbx. Each entry point finishes by executing a hook; gdb-mode-hook,
sdb-mode-hook or dbx-mode-hook respectively.
After startup, the following commands are available:
\\{gud-mode-map}
\\[gud-display-frame] displays in the other window
the last line referred to in the gud buffer.
\\[gud-refresh] displays in the other window the last line referred to
in the gud buffer.
\\[gud-step],\\[gud-next], and \\[gud-nexti] in the gud window,
\\[gud-step], \\[gud-next], and \\[gud-stepi] in the gud window,
do a step-one-line, step-one-line (not entering function calls), and
step-one-instruction and then update the other window
with the current file and position. \\[gud-cont] continues
execution.
If you are in a source file, you may set a breakpoint at the current
line in the current source file by doing \\[gud-break].
The above commands are common to all supported debuggers. If you are
using gdb or dbx, the following additional commands will be available:
\\[gud-up] pops up through an enclosing stack frame. \\[gud-down] drops
back down through one.
If you are using gdb, \\[gdb-finish] runs execution to the return from
the current function and stops.
These functions repeat themselves the appropriate number of times if you give a
prefix argument.
If you are in a source file, you may do the following:
Set a breakpoint at the current line by doing \\[gud-break]. This causes
an appropriate set-break to be send to the debugger; of course, if the file
you're visiting doesn't correspond to any code in the executable this will
have no effect or raise an error.
Commands:
Many commands are inherited from comint mode.
Additionally we have:
Execute a user-defined command at point with \\[send-gud-command]; the
prefix argument is taken as an index into the list of strings gud-commands.
A %s in a gud-commands string is substituted with a number or address picked
up from point.
\\[gud-display-frame] display frames file in other window
\\[gud-step] advance one line in program
\\[gud-next] advance one line in program (skip over calls).
\\[send-gud-command] used for special printing of an arg at the current point.
C-x SPACE sets break point at current line."
Other commands for interacting with the debugger process are inherited from
comint mode, which see."
