!ubl

The !ubl extension lists all user-space breakpoints and their current status.

!ubl

DLL

Windows 2000	Kdextx86.dll
Windows XP and later	Kdexts.dll

Remarks

Here is an example of the use and display of user-space breakpoints:

kd> !ubp 8014a131
This command is VERY DANGEROUS, and may crash your system!
If you don't know what you are doing, enter "!ubc *" now!

kd> !ubp 801544f4

kd> !ubd 1

kd> !ubl
 0: e ffffffff`8014a131 (ffffffff`82deb000) 1 ffffffff
 1: d ffffffff`801544f4 (ffffffff`82dff000) 0 ffffffff

Each line in this listing contains the breakpoint number, the status (e for enabled or d for disabled), the virtual address used to set the breakpoint, the physical address of the actual breakpoint, the byte position, and the contents of this memory location at the time the breakpoint was set.
