Specific error codes listed in the descriptions of each Grexxxfunction are found in Mandatory and Simulated Graphics Engine Function Reference.
To set an error code and the error's severity, the presentation driver must call WinSetErrorInfo (see WinSetErrorInfo). All error codes are listed and explained in the Presentation Manager Programming Reference.
