LeapMotion eLeapRS_InvalidClientID occurring unexpectedly

[gavinnop]

Hi,

I've tried implementing the orion LeapC API. The create and open connection functions are successful. however, on the first call to LeapPollConnection, it returns eLeapRS_InvalidClientID, and after that, it times out every time it is called.

Is there something I'm overlooking that could cause this?

Relevant note: I'm using C++ and put the header files in an extern "C" wrapper.

Here's some more clarification:

I’m having an issue with my LeapC application.
With the following function:
void Leap::Initialize()
{
eLeapRS result = LeapCreateConnection(NULL, &connectionHandle);
if (result == eLeapRS_Success)
{
result = LeapOpenConnection(connectionHandle);
if (result == eLeapRS_Success)
{
_bIsRunning = true;
_bTerminateThread = false;
_bFreezeThread = false;
LEAP_CONNECTION_MESSAGE msg;
result = LeapPollConnection(connectionHandle, 100, &msg);
…
}
}
}
I get eLeapRS_InvalidClientID fo the result from LeapPollConnection

Sorry, for the poor formatting, I tried to indent, but they were removed, and I can't seem to edit previous posts.

Can you confirm whether it does this when you compile the C++ example? One of our engineers advised being sure not to forget any arguments when opening the connection.
