Purpose

Note UnMapPhysicalMemory requires the LabWindows/CVI low-level support driver. LabWindows/CVI loads the driver at startup if it is on disk. You can check whether LabWindows/CVI loaded the driver at startup by calling CVILowLevelSupportDriverLoaded. The low-level support driver is not supported on 64-bit systems. Only applications running with administrator privileges on 32-bit systems can load the low-level support driver. |
