.SH DESCRIPTION
|
|
.B winedbg
|
|
is a debugger for Wine. It allows:
|
|
.RS 4
|
|
.nf
|
|
+ debugging native Win32 applications
|
|
+ debugging Winelib applications
|
|
+ being a drop-in replacement for Dr Watson
|
|
.fi
|
|
.RE
|
|
.PP
|
|
|
|
.SH MODES
|
|
\fBwinedbg\fR can be used in five modes. The first argument to the
|
|
program determines the mode winedbg will run in.
|
|
.IP \fBdefault\fR
|
|
Without any explicit mode, this is standard \fBwinedbg\fR operating
|
|
mode. \fBwinedbg\fR will act as the front end for the user.
|
|
.IP \fB--gdb\fR
|
|
\fBwinedbg\fR will be used as a proxy for \fBgdb\fR. \fBgdb\fR will be
|
|
the front end for command handling, and \fBwinedbg\fR will proxy all
|
|
debugging requests from \fBgdb\fR to the Win32 APIs.
|
|
.IP \fB--auto\fR
|
|
This mode is used when \fBwinedbg\fR is set up in \fIAeDebug\fR
|
|
registry entry as the default debugger. \fBwinedbg\fR will then
|
|
display basic information about a crash. This is useful for users
|
|
who don't want to debug a crash, but rather gather relevant
|
|
information about the crash to be sent to developers.
|
|
.IP \fB--minidump\fR
|
|
This mode is similar to the \fB--auto\fR one, except that instead of
|
|
printing the information on the screen (as \fB--auto\fR does), it's
|
|
saved into a minidump file. The name of the file is either passed on
|
|
the command line, or generated by \fBWineDbg\fR when none is given.
|
|
This file could later on be reloaded into \fBwinedbg\fR for further
|
|
examination.
|
|
.IP \fBfile.mdmp\fR
|
|
In this mode \fBwinedbg\fR reloads the state of a debuggee which
|
|
has been saved into a minidump file. See either the \fBminidump\fR
|
|
command below, or the \fB--minidump mode\fR.
|
|
|
|
.SH OPTIONS
|
|
When in \fBdefault\fR mode, the following options are available:
|
|
.PP
|
|
.IP \fB--command\ \fIstring\fR
|
|
\fBwinedbg\fR will execute the command \fIstring\fR as if it was keyed on
|
|
winedbg command line, and then will exit. This can be handy for
|
|
getting the pid of running processes (winedbg --command "info proc").
|
|
.IP \fB--file\ \fIfilename\fR
|
|
\fBwinedbg\fR will execute the list of commands contained in file
|
|
filename as if they were keyed on winedbg command line, and then
|
|
will exit.
|
|
.PP
|
|
When in \fBgdb\fR proxy mode, the following options are available:
|
|
.PP
|
|
.IP \fB--no-start\fR
|
|
\fBgdb\fR will not be automatically
|
|
started. Relevant information for starting \fBgdb\fR is printed on
|
|
screen. This is somehow useful when not directly using \fBgdb\fR but
|
|
some graphical front-ends, like \fBddd\fR or \fBkgbd\fR.
|
|
.IP \fB--port\fR\ \fIport\fR
|
|
Start the \fBgdb\fR server on the given port. If this option is not
|
|
specified, a randomly chosen port will be used. If \fB--no-start\fR is
|
|
specified, the port used will be printed on startup.
|
|
.IP \fB--with-xterm\fR
|
|
This will run \fBgdb\fR in its own xterm instead of using the current
|
|
Unix console for textual display.
|
|
.PP
|
|
In all modes, the rest of the command line, when passed, is used to
|
|
identify which programs, if any, has to debugged:
|
|
.IP \fIprogram_name\fR
|
|
This is the name of an executable to start for a debugging
|
|
session. \fBwinedbg\fR will actually create a process with this
|
|
executable. If \fIprograms_arguments\fR are also given, they will be
|
|
used as arguments for creating the process to be debugged.
|
|
.IP \fIwpid\fR
|
|
\fBwinedbg\fR will attach to the process which Windows pid is \fIwpid\fR.
|
|
Use the \fBinfo proc\fR command within \fBwinedbg\fR to list running processes
|
|
and their Windows pids.
|
|
.IP \fBdefault\fR
|
|
If nothing is specified, you will enter the debugger without any run
|
|
nor attached process. You'll have to do the job yourself.
|
|
|
|
.SH COMMANDS
|
|
.SS Default mode, and while reloading a minidump file:
|
|
.PP
|
|
Most of commands used in \fBwinedbg\fR are similar to the ones from
|
|
\fBgdb\fR. Please refer to the \fBgdb\fR documentations for some more
|
|
details. See the \fIgdb\ differences\fR section later on to get a list
|
|
of variations from \fBgdb\fR commands.
