System Error Codes are defined errors and error codes that are utilized by programmers when their software has an issue. They can be displayed by a computer to users in response to software problems and hardware issues, or even certain kinds of input from users. Error codes in systems are usually displayed as an acronym, with a description of the error along with the suggestion of what to do next.
These error codes are displayed on the Internet when a website is not accessible, or if there is an internal server problem or data base issue. On a local machine the error could be as simple as “file too long” where the solution is changing the file’s name, or more complex like “no space left on the disk.” In this situation you might need to shut down certain applications (to remove swap files), delete some data, or purchase an additional hard disk.
Other system problems could be as serious as “fatal error,” in which a program has decided to stop or quit, but they may also be as simple as an alert that something isn’t working. The majority of errors that be experienced on the GNU/Hurd system is represented by an error message in the header file Errno.
These errors can range from the simple “text file busy” when an operation attempts to modify a read-only file, to the more intricate “broken pipeline.” These errors could also mean that the process trying to perform on the resource has been interrupted by a signal such SIGPIPE, and is not being handled.
