.SH MODES
\fBwinedbg\fR can be used in three modes. The first argument to the
\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--auto\fR
This mode is used when \fBwinedbg\fR is setup 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--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
This mode allows to reload into \fBwinedbg\fR 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.
