1. The error message includes an error code, which in case the user wishes to use it is also returned by the function. If there was no licensing error the function returns 0.
2. It's recommended that you pass a buffer of at least 2048 bytes as licensing errors can be qute long. If the error message is too large to fit in the buffer, the first maxbytes-1 characters will be returned.
