Show windbg debugging information

Show windbg debugging information

Windbg is a debugger, but it is also a software and has bugs, as if the doctor is also ill. How can I debug windbg? Designers of windbg have considered this early. For example, the. dbgdbg command is to start a debugger to debug the current debugger.

Another example is to use the. outmask command to allow windbg to output debugging information. Parameters can be a combination of the Flag spaces in the following table.

Value	Default setting	Description
1	On	Normal output
2	On	Error output
4	On	Warnings
8	Off	Additional output
0x10	On	Prompt output
0x20	On	Register dump before prompt
0x40	On	Warnings that are specific to extension operation
0x80	On	Debug output from the target (for example,OutputdebugstringOrDbuplint)
Zero x 100	On	Debug input expected by the target (for example,Dbgprompt)
Zero X 200	On	Symbol messages (for example,! Sym noisy)

For simplicity, using 0xffffffff as the parameter means to open all debugging output. It is too troublesome to input 8 F, so use the/a switch:

0: 000>. outmask/
Client 007b5a60 mask is ffffffff

After executing the preceding command, restore the debugging target and you will see many internal processes of windbg's work.
