The callstack view

 

The callstack view shows a snapshot of the callstack for any thread in your application as the program runs.

 

The callstack is displayed in a columnar format with the following information in each level in the stack

 

•Thread: the id of the thread, or the name if one has been set

 

•Address: the address of the function

 

•Module: the DLL or executable name

 

•Symbol: the symbol of the method or function

 

•Filename: the path to the file containing the function, including line number

 

The display can be updated automatically from every 20ms to every 2s or only on demand.

 

If the threads in your application have been named (see how) then those names are displayed in the thread list so that you can identify them.

 

Alternatively, use the Thread Names dialog below, to assign names to the threads for the duration of the session.

Thread names

 

If a thread has been named using the Win32 RaiseException method, the Win32 SetThreadDescription(), or using pvSetThreadName() its name is shown in the list. See the link below for more details.

 

For threads not explicitly named by the above methods, Performance Validator provides automatically generated names based on the name of the function passed to CreateThread(), _beginthread(), or _beginthreadex(). If you want to give a thread a name here by double clicking on the name column and entering a name for the thread. Click outside the box or press return to complete the entry.

 

How can I give a name to a thread from my code?
