System Error Codes

System Error Codes are pre-defined error codes and errors messages that are utilized by programmers when their software has an issue. They can be displayed by computers to users in response to software issues, hardware issues, or even specific types of user input. System error codes are typically displayed as an acronym with an explanation of the error and a suggestion for what to do next.

These error codes are commonly seen on the internet if a web page is not available or if an internal server issue occurs for instance, an issue with databases. On a local machine the error could be as simple as “file too long” and the solution is changing the file’s name, or more complex such as “no space left on the disk.” In this instance it is possible to close certain applications (to clear swap files) or erase some files, or buy an extra hard disk.

Other system issues could be as severe as “fatal error,” in which a program has decided to quit or give up, but they can also be as subtle as a warning that something isn’t quite right. Nearly every error that could occur on the GNU/Hurd system is represented by an error coding in the header file errno.

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 could also mean that the process trying to work on the resource has been interrupted by a signal like SIGPIPE, and is not being taken care of.
