Values - Remarks - C/C++ example
This method returns the neoVI hardware devices connected to the PC.
int
icsneoFindNeoDevices(unsigned long DeviceTypes, NeoDevice *pNeoDevices, int *pNumberOfDevices);DeviceTypes
[in] Specifies the types of neoVI devices to find. Currently supported
values are:
NEODEVICE_FIRE
8
NEODEVICE_VCAN3
16
NEODEVICE_YELLOW
32
NEODEVICE_ALL
65535
These values are defined in the icsnVC40.h file.
You
may use logical OR to choose which devices to look for or use NEODEVICE_ALL to
specify all devices.
pNeoDevices
[out] This is the address of the first element of an array of NeoDevice
structures (defined in icsnVC40.h). This array should big enough to hold 255
devices. You must specify the size of the pNeoDevices array in the
pNumberOfDevices parameter. The number of devices found will be limited to the
value of pNumberofDevices or 255, whichever is lower. Each returned NeoDevice
structure will contain information for each device such as its type, device
‘handle’ and serial number.
pNumberOfDevices
[in/out] In: Specifies the size of the pNeoDevices array.
Must be in the range 0 to 255.
Out: Specifies the number of neo devices that were found. This can be in the
range 0 to 255.
1 if the
function succeeded. 0 if it failed for any reason. If the function succeeds but
no devices are found 1 will still be returned and pNumberOfDevices will equal 0.
The NeoDevice array elements that are returned with
this function may be passed to OpenNeoDevice
so that
individual neoVI devices can be opened.
Example
NeoDevice Devices[255];
unsigned long lDevTypes = NEODEVICE_VCAN3 | NEODEVICE_FIRE;
int iNumDevices = 255;
int iRetVal = 0;
//Search for just ValueCAN3 and FIRE
iRetVal = icsneoFindNeoDevices(lDevTypes, Devices, &iNumDevices);
//Search for all supported neoVI types
iRetVal = icsneoFindNeoDevices(NEODEVICE_ALL, Devices,
&iNumDevices);
