Runtime - Wikipedia, the free encyclopedia (529 words)
The term is also used as a short form when referring to a runtime library (without a space), a program or library of basic code that is used by a particular computer language to manage a program written in that language while it is running.
A runtime library is a collection of utility functions which support a program while it is running, working with the operating system to provide facilities such as mathematical functions, input and output.
Exception handling is one language feature designed to handle runtime errors, providing a structured way to catch completely unexpected situations as well as predictable errors or unusual results without the amount of inline error checking required of languages without it.
