Threads Window (Windows Embedded CE 6.0)
1/5/2010
The Threads window shows the threads, or paths of execution, within the process selected from the Process drop-down list. Using this dialog box, you can:
- View the thread handle and the handle of the process that created the thread
- View thread states
- Display thread priority
- Display elapsed time used by the thread
- **
When the Debugger Is Running
The following types of information are displayed in the Threads window when the debugger is running.
| Item | Description |
|---|---|
BasePrio |
Base (unadjusted) thread priority. |
CurPrio |
Current (possibly inversion adjusted) thread priority. |
hActvProc |
Handle to active process. |
hOwnerProc |
Handle value of the process which created the thread. |
hThread |
Handle value associated with the thread. |
hVMProc |
Handle value of the process that the thread is currently running in (can change on system calls). |
InfoStatus |
Thread status information.
Item Description
UModeUser mode thread (set at thread creation time).
KModeKernel mode thread (set at thread creation time).
StkFltStack overflow exception occurred in the thread.
UsrBlkdThread is stopped by user action (thread suspend, sleep, sync, etc.)
ProfdThread Profiling (deprecated).
|
KernelTime |
The amount of CPU time spent by the thread in kernel mode. KernelTime starts from the beginning of the creation of the thread until the current snapshot is taken. |
LastError |
Pointer to thread's last error value (SetLastError() / GetLastError() values). |
PC |
Thread's program counter (current instruction memory location). |
pThread |
Pointer to kernel thread data structure describing the thread. |
Quantum |
Thread's quantum time (maximum time a thread can run without preemption - in milliseconds). |
QuantumLeft |
Thread time left before preemption due to quantum expiration (in milliseconds). |
RunState |
Thread's execution state. See Run State table below. |
SleepCount |
The system tick count at which a thread should be done sleeping/waiting. |
StackBase |
End of stack (stack grows to StackBase). |
StkLowBnd |
Current lower bound of committed stack. |
StkRetAddr |
Return address on stack. |
SuspendCount |
Count of how many times a thread has been suspended (SuspendThread API). |
ThreadName |
The name of the module and initial thread function. |
TlsPtr |
Pointer to thread's local storage (TLS) area. |
UserTime |
The amount of CPU time the thread used in user mode. UserTime starts from the beginning of the creation of the thread until the current snapshot is taken. |
WaitState |
Thread signal state.
Item Description
SignalledThread has been signaled by an external event.
ProcessingAn event has occurred or priority changed that might require re-processing the wait state.
BlockedThread is waiting on an external event.
|
The following table shows the thread state values.
| Run State Value | Description |
|---|---|
Dying |
Thread has been terminated in-flight during a system call, will exit upon return of system call. |
Dead |
Thread has been terminated, cleanup work is pending. |
Buried |
Thread has been terminated and all resources cleaned up. |
Slpg |
Thread is sleeping. |
Awak |
Thread is not sleeping or blocked. |
Rung |
Thread is currently running. |
Runab |
Thread is in runnable state (thread is in run queue and can be scheduled to run when it comes to the front of the queue). |
RunBlkd |
Thread is blocked. |
RunNeeds |
Thread is out of block queue, but not yet put in run queue. |
