System Error Codes

System Error codes are error messages and error codes that programmers are able to use when their software is having problems. They are displayed to users of the computer system in response to hardware issues, software issues, and even certain kinds of input by the user. Error codes in systems are usually displayed as an acronym along with an explanation of the error along with a suggestion for what to do next.

These error codes are usually seen on the internet when websites are not accessible or when an internal server issue arises like an issue with databases. On a local machine the error could be as simple as “file too long” which can be resolved by changing the name of the file, or more complex like “no space left on the disk.” In this scenario the user might need to close the program (to free swap file usage) or erase some files, or purchase an extra hard drive.

Other system errors can be as severe as “fatal error,” where a program has decided to shut down and quit and stop. It could also be as light as a signal that something isn’t working in an operation. The header file errno includes error codes for almost every possible error in the GNU/Hurd operating system.

These errors could 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 errors may also indicate that the function attempting to work on the resource has been interrupted by a signal like SIGPIPE and not properly addressed.
