In the UNIX world, exception handling mechanisms for eror handling are often discussed, but seldom applied. This paper describes a disciplined approach to error handling thar was refined over a !-year perioO during the development of a medium-large (200K line) toolkit written in C under UNIX We describe both a portable exception handing system, written in C, and a methodology for using it which...

Reliability is essential in systems software. A key element of ensuring reliability is proper handling of error conditions [26]. In general, the role of error handling code is to return the system to a coherent state, typically by undoing recent operations and releasing recently allocated resources. If some of these resource-releasing operations are omitted, the result can be deadlocks and memo...

Incorrect error handling in security-sensitive code often leads to severe security vulnerabilities. Implementing correct error handling is repetitive and tedious especially in languages like C that do not support any exception handling primitives. This makes it very easy for the developers to unwittingly introduce error handling bugs. Moreover, error handling bugs are hard to detect and locate ...

Problems come up during software development all the time. When developers hit these bumps, they must figure out what has gone wrong. Findings from three studies suggest that way handle errors contributes to professional growth.
