Attaching the debugger to a running application

Nsight debugger can attach to an application that is already running on the same system. This application can be built and run outside of the Nsight and its source files are not required to be visible in Nsight workbench.

To attach to a running application:

1. From the Run menu select Attach. Note that this menu item may not be present on perspectives other then C/C++, Debug or Profile
2. A dialog will open where you can lookup the application you want to attach to. You can use filter field to find the application by its name. Select the application and click OK
3. Debugger will attach to the selected application and will suspend its execution.

Application source file will be opened in editor area and current line will be highlighted. You can now use debugger controls to explore application state and resume its execution.

Debug session will end when either an application was ran to a completion, application was terminated using debugger controls or the debugger was disconnected from the application.
