What do the return values from the engOpen and engOpenSingleUse functions mean when there is a failure to open MATLAB?

I am trying to use the MATLAB engine from my C application to call into MATLAB . However, my application fails to open MATLAB when I use the engOpenSingleUse function. It returns a failure code, but I cannot determine what the return value means.

There are only three return results for the engOpenSingleUse function:
0 = success
-2 = error - second argument must be NULL
-3 = error - engOpenSingleUse failed
You should try reregistering MATLAB on those systems that it fails on, as shown here:

For more information on the engOpenSIngleUse function, issue the following command at the MATLAB prompt:
doc engOpenSingleUse
