4/6F.4 Error codes
The error codes returned by the Hyper-G Server are divided into three groups, corresponding to the server module that generated the error:
- Error codes between 1 and 511 are link server errors.
- Error codes between 512 and 1023 are full text server errors.
- Error codes between 1024 and 2047 are document cache
server errors.
An error code of 0 means that no error occurred.
The following table shows the link server error codes with their associated mnemonic names and a short (human-readable) description that could be output on a terminal, for example.
