How about having Arduino IDE ship with an include file with standard error codes that could be used by libraries and sketches: #ifndef ERRORCODES_H #define ERRORCODES_H //! \version 1.2 enum ErrorCode { SUCCESS= 0, ERROR_CHECKSUM= -9999, ERROR_TIMEOUT= -9998, …

How about standard Error Codes?

I changed two of my libs on the playground with error codes in the .h file

improved the readability of the example and I could remove some comments explaining magic numbers
