Debugging with GDB Manual HP WDB v6.3 (5900-2180, August 2012)

To save a session to a file:
1. Right-click an empty region of the source or debugger pane.
2. Choose "Save Session to vdb.pid" from the pop-up menu.
The debugger writes the input and output to a file whose name ends in the pid of the debugger.
If you save the session more than once, the new transactions are appended to the file.
14.33 Support for ddd
GDB works with ddd, the free GDB GUI shell available at http://mumm.ibr.cs.tu-bs.de/. While
this is not formally supported by Hewlett-Packard, these two do work together. Note however if
you have ddd issues, you'll need to report them to the ddd support channel.
14.34 Support for XDB commands
HP WDB provides support for a subset of XDB commands, enabled with the -xdb option.
14.34.1 stop in/at dbx commands
The commands <stop in function/address> and <stop at line> are equivalent of
dbx <break function/address /line> command. HP WDB supports the <stop in/at>
command in non-dbx mode.
For example:
$ gdb a.out (gdb) stop in main Breakpoint 1 at 0x2a34: file list.c, line 18
from /tmp/a.out (gdb) stop at 25 Breakpoint 2 at 0x2a6c: file list.c, line
25 from /tmp/a.out (gdb)
