Run-time locking

You can edit, save, and compile any user module in the user library while one of its user modules is

being run. However, run-time user-library locking prevents building of KULT user library while one of

its user modules is being run in Clarius. If you try, you see the message "This library cannot be built

because it is currently locked out."

Run-time lock files are generated in the following directory:

%KI_KULT_PATH%\lock

When Clarius executes a UTM, a run-time lock file is automatically created during the normal loading

of the user module. The run-time lock file is automatically deleted at the end of the run during normal

unloading of the user module.

Removing locks that remain after interrupted operation

If normal operation of KULT or normal execution of user libraries is interrupted, the protective locks

may not be removed automatically. However, you can remove locks manually via the

kultcleanlocks command-line utility. This utility deletes all lock files in both of the following

directories:

%KI_KULT_PATH%\lock

%KI_KULT_PATH%\<library_name>\lock

Execute the kultcleanlocks utility as follows:

1. Click the Command Prompt icon on the desktop or in the Start > Programs menu. The

Command Prompt window opens.

2. At the Command Prompt, type kultcleanlocks.

3. Press Enter. The kultcleanlocks utility executes and deletes all residual lock files.

Debugging user modules using Microsoft Visual C++

You can use the 4200-COMPILER, which is Microsoft

debug KULT modules, including user library and user modules. It allows you to develop test

subroutine libraries using the full capabilities of C-language programming.

If 4200-COMPILER was ordered with your 4200A-SCS system, the software is installed by Keithley

Instruments. You can also purchase the 4200-COMPILER later. Refer to document number

PA-1030, Compiler Installation Instructions, for detail on how to install.

At times you may need to perform step-by-step debugging of a library user module, using the

capabilities of Microsoft

create_dt command-line utility. The create_dt utility automatically generates a small Microsoft

Visual C++ program, called a debug task, in which to test and debug your module.
