The list of API error codes can be found in PixeLINK\include\PixeLINKCodes.h after installing Pixelink SDK.


NOTE: It is highly recommended that the API_SUCCESS() macro be used to test for success, rather than doing a direct comparison to ApiSuccess.


An example using the API_SUCCESS macro:


 HANDLE hCamera;
 PXL_RETURN_CODE rc = PxLInitialize(0, hCamera);
 if (API_SUCCESS(rc)) {
     // We were able to connect to a camera
 }

   

With .NET:


 int hCamera = 0;
 ReturnCode rc = Api.Initialize(0, ref hCamera);
 if(Api.IsSuccess(rc)) {
    // We were able to connect to a camera
 }



Return Code
Value
Explanation
Possible Reasons
ApiSuccess0x00000000
The function completed successfully.

ApiSuccessParameterChanged
0x00000001

ApiSuccessWhiteBalance
TooDark
0x00000007
The Auto WhiteBalance algorithm could not achieve good results because the auto-adjust area is too dark.

ApiSuccessWhiteBalance
