.extpath (Set Extension Path)

The .extpath command sets or displays the extension DLL search path.

.extpath[+] [Directory[;...]]

Parameters

+

Signifies that the debugger should append new directories to the previous extension DLL search path (instead of replacing the path).

Directory

Specifies one or more directories to put in the search path. If you do not specify Directory, the current path is displayed. You can separate multiple directories with semicolons.

Environment

Modes

User mode, kernel mode

Targets

Live, crash dump

Platforms

All

 

Additional Information

For more information about the extension search path and loading extension DLLs, see Loading Debugger Extension DLLs.

Remarks

The extension DLL search path is reset to its default value at the start of each debugging session.

During live kernel-mode debugging, a reboot of the target computer results in the start of a new debugging session. So any changes that you make to the extension DLL search path during kernel-mode debugging will not persist across a reboot of the target computer.

The default value of the extension DLL search path contains all the extension paths known to the debugger and all the paths in the %PATH% environment variable. For example, suppose your %PATH% environment variable has a value of C:\Windows\system32;C:\Windows. Then the default value of the DLL extension search path might look like this.

0:000> .extpath
Extension search path is: C:\Program Files\Debugging Tools for Windows (x64)\WINXP;C:\Program Files\
Debugging Tools for Windows (x64)\winext;C:\Program Files\Debugging Tools for Windows (x64)\winext\
arcade;C:\Program Files\Debugging Tools for Windows (x64);C:\Program Files\Debugging Tools for 
Windows (x64)\winext\arcade;C:\Windows\system32;C:\Windows
