inp

char inp (short portNumber);

Purpose

Note  This function is obsolete.

Reads a byte from a port.

Note If you include this function in your program, the program will require administrator privileges to run. inp 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.

Caution  The Windows SDK also contains a function with the same name. Include windows.h before including utility.h to ensure that there are no compilation errors as a result of this naming conflict. Define the SDK_CONFLICT_PRIORITYSDK_CONFLICT_PRIORITY macro to force LabWindows/CVI to use the Windows SDK implementation of this function.
