System Error codes are messages of error and error codes that programmers are able to use when their software is having an issue. They can be displayed to the users of a computer system in response to hardware issues, software issues, or certain kinds of input by the user. The error codes for system errors are usually displayed as an acronym along with a description of the error along with a suggestion for what to do next.
These error codes are usually seen on the internet if a web page is not accessible or when an internal server issue occurs for example, an issue with databases. On a local computer they can 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 the disk.” In this case, the user may need to close the program (to free swap use of files) or delete certain files, or buy a bigger hard drive.
Other system issues can be as serious as “fatal error,” where a program has decided to shut down and give up, or as mild as a warning that something isn’t right with an operation. The header file errno contains error codes for virtually every possible error on the GNU/Hurd operating system.
These errors can be as simple as “text file busy,” where the operation is attempting to modify a read-only file or as complicated as “broken pipe.” These types of errors could also mean that the function trying to run on the resource check this has been interrupted by a SIGPIPE message and was not dealt with.
