Defrag Tools - Season 1 Episode 26 WinDbg - Semaphores, Mutexes and Timers
0.00 45 minutes In this episode of Defrag Tools, Andrew Richards, Chad Beeder and Larry Larsen continue looking at the Debugging Tools for Windows (in particular WinDbg). WinDbg is a debugger that supports user mode debugging of a process, or kernel mode debugging of a computer.
This installment goes over the commands used to diagnose Semaphores, Mutexes and (Waitable) Timers in a user mode application. For timers, we delve deep in to the kernel to gather more information about them. We use these commands:
!handle
!handle
!object
!object
!timer
!timer
ub @rip
dt nt!_KTHREAD
Make sure you watch Defrag Tools Episode #1 and Defrag Tools Episode #23 for instructions on how to get the Debugging Tools for Windows and how to set the required environment variables for symbol and source code resolution.
