OpenNeoDevice Method - intrepidcs API
C/C++ declare - Parameters - Return Values - Remarks - C/C++ example

This method opens a communication link the a neoVI device.

C/C++ Declare

int icsneoOpenNeoDevice(NeoDevice *pNeoDevice, int *hObject, unsigned char *bNetworkIDs, int bConfigRead, int bSyncToPC);


Parameters

pNeoDevice
    [in] A valid NeoDevice structure filled with information about a specific neoVI device. This must be obtained by calling FindNeoDevices.

hObject
    [out] The address of an int value. This will be set to the handle of the neoVI driver object that is created. It is needed as an input parameter to other API function calls.   Every time you create a new neoVI object you must call ClosePort and FreeObject to avoid creating a memory and resource leak.

bNetworkIDs
   [in] This is an array of number IDs which specify the NetworkID parameter of each network. This allows you to assign a custom network ID to each network. Normally, you will assign consecutive IDs to each of the networks. See NetworkIDList for a list of current network ID's. You may also set this parameter to NULL (zero) and the default network ID's will be used.

bConfigRead
    [in] Specifies whether the DLL should read the neoVI's device configuration before enabling the device. It is recommended that this value be set to 1.

 bSyncToPC
    [in] Not supported

Return Values

If the port has been opened successfully,  the return value will be 1. Otherwise the return value will be zero. 

Remarks

Each successful call to OpenNeoDevice should be matched with a call to the  ClosePort and FreeObject methods. 

Example

C/C++ Example

int hObject = 0;  // holds a handle to the neoVI object
int iRetVal;
int iCount;
NeoDevice *pDevice = pParmIn; //created previously       

iRetVal = icsneoOpenNeoDevice(pDevice, &hObject, NULL, 1, 0);
