print routines so as to allow Epoch to display values of
expressions in a separate window.

-annotate level

This option sets the annotation level inside GDB. Its effect
is identical to using `set annotate level' (see

“GDB

Annotations” (page 297)

). Annotation level controls how

much information does GDB print together with its
prompt, values of expressions, source lines, and other
types of output. Level 0 is the normal, level 1 is for use
when GDB is run as a subprocess of GNU Emacs, level 2
is the maximum annotation suitable for programs that
control GDB.

-async

Use the asynchronous event loop for the command-line
interface. GDB processes all events, such as user

1

keyboard input, via a special event loop. This allows
GDB to accept and process user commands in parallel
with the debugged process being run

1

, so you do not

need to wait for control to return to GDB before you type
the next command.

NOTE:

As of version 5.0, the target side of the

asynchronous operation is not yet in place, so '-async'
does not work fully yet.

When the standard input is connected to a terminal
device, GDB uses the asynchronous event loop by
default, unless disabled by the '-noasync' option.

-noasync

Disable the asynchronous event loop for the
command-line interface.

-baud bps

, -b bps

Set the line speed (baud rate or bits per second) of any
serial interface used by GDB for remote debugging.

-tty device

, -t device Run using device for your program's standard input and

output.

-tui

Use a Terminal User Interface. For information, use your
Web browser to read the file 'tui.html', which is
usually installed in the directory /opt/langtools/
wdb/doc

on HP-UX systems. Do not use this option if

you run GDB from Emacs (see

“Using GDB under gnu

Emacs” (page 293)

).

-xdb

Run in XDB compatibility mode, allowing the use of
certain XDB commands. For information, see the file

1. GDB built with DJGPP tools for MS-DOS/MS-Windows supports this mode of operation, but the event

loop is suspended when the debug target runs.
