CVILowLevelSupportDriverLoaded

int CVILowLevelSupportDriverLoaded (void);

Purpose

Note  This function is obsolete.

Indicates whether the LabWindows/CVI low-level support driver was loaded at startup. The following Utility Library functions require the LabWindows/CVI low-level driver:

• inp
• inpw
• inpd
• outp
• outpw
• outpd
• ReadFromPhysicalMemory
• ReadFromPhysicalMemoryEx
• WriteToPhysicalMemory
• WriteToPhysicalMemoryEx
• MapPhysicalMemory
• UnMapPhysicalMemory

Note   Most of these functions do not return an error if the low-level support driver is not loaded. To make sure your calls to these functions can execute correctly, call CVILowLevelSupportDriverLoaded at the beginning of your program.

(Linux) This function is not supported.

The LabWindows/CVI libraries automatically load the low-level support driver at startup if it is on disk. The low-level support driver ships with LabWindows/CVI. Enable the Low-Level Support Driver option on the Edit Installer dialog box Drivers & ComponentsDrivers & Components tab to include the driver with your stand-alone executables or DLLs.

Note  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.
