Resources Tracked in the Resource Tracking Window
The Resource Tracking window only tracks resources that you must explicitly free and that do not belong to other resources. For example, the Resource Tracking window does not track user interface controls because the controls are owned by panels and are freed when the panel is freed.
The Resource Tracking window tracks the following types of resources in the standard LabWindows/CVI libraries and listed instrument drivers:
 |
Note Individual driver libraries might track resources in addition to the ones listed in this topic. |

Network Streams Library
|
Note You must call the CNSFinish function after your program is done using the Network Streams Library to discard and clean up global resources. If you do not call this function after calling other functions in the Network Streams Library, your program might hang or crash when it closes and LabWindows/CVI might not be able to report the leaked resources in your program. |
- Endpoints
- Data objects
- Strings
- Arrays
Network Variable Library
|
Note You must call the CNVFinish function after your program is done using the Network Variable Library to discard and clean up global resources. If you do not call this function after calling other functions in the Network Variable Library, your program might hang or crash when it closes and LabWindows/CVI might not be able to report the leaked resources in your program. |
