# ERRORCODE

Description | The most recent Optimizer error number that occurred. This is useful to determine the precise error that has occurred, after an Optimizer function has signalled an error by returning a non-zero value. The return value itself is not the error number. Refer to Optimizer Error and Warning Messages for a list of possible error numbers, the errors they indicate, and advice on what they mean and how to resolve them. A short error message may be obtained using XPRSgetlasterror, and all messages may be intercepted using the user output callback function; see XPRSaddcbmessage.
