Returned status: 0 on success, negative number on failure. |
The MArvin Test Solutions HW device driver is installed with the driver and is the default device driver. The function returns a handle that is used with other Counter functions to program the board. The function does not change any of the board settings.
The specified PXI slot number is displayed by the PXI/PCI Explorer applet that can be opened from the Windows Control Panel. You may also use the label on the chassis below the PXI slot where the board is installed. The function accepts two types of slot numbers:
A combination of chassis number (chassis # x 256) with the chassis slot number. For example 0x105 (chassis 1 slot 5).
A Legacy nSlot is used by earlier versions of HW/VISA. The slot number contains no chassis number and can be changed using the PXI/PCI Explorer applet (1-255).
The following example initializes two GX1120 boards at slot 7 and 8.
SHORT nHandle1, nHandle2, nStatus;
GtWaveInitialize (7, &nHandle1, &nStatus);
GtWaveInitialize (8, &nHandle2, &nStatus);
if (nHandle1==0 || nHandle2==0)
{ printf(“Unable to Initialize the boards”)
return;
}
