System Error codes are error messages and errors that programmers can use to help their software when it is experiencing a problem. They can be displayed to users of a computer system in response to hardware or software issues, or some kinds of input from the user. The system error codes are displayed as an acronym, together with a description and suggestions of what to do next.

These errors can be seen on the internet when a website isn’t accessible, or if there is an internal server issue like a data base issue. If you are using a local computer such errors could be as simple as «file too long,» where the solution is to change the file’s name or more complex, such as «no space left on disk.» In this instance it is possible for the user to shut down programs (to free swap file usage) or delete some files, or purchase a bigger hard drive.

Other system errors may be as severe as «fatal error,» in which a program has decided to quit or stop, but they can also be as subtle as a signal that something isn’t quite right. The header file errno contains errors for almost every possible error on the GNU/Hurd operating system.

These errors can range from simple «text file busy» when an operation attempts to modify a read only file, to the more intricate «broken pipeline.» These errors may also indicate that the function trying to run on the resource has been interrupted by a signal like SIGPIPE and not properly taken care of.
