Syntax

#include <AnaGateDllSPI.h>

int SPICloseDevice(int hHandle);

Parameter

hHandle Valid access handle.

Return value

Description

Closes an open network connection to an AnaGate SPI device. The hHandle parameter is a return value

of a succesfull call to the function SPIOpenDevice.

are freed again and the connected AnaGate device is signalled that the active connection is

not longer in use and can be used again for new connect requests.
