Utilities

Useful functions that are not specifically tied to a certain topic or domain are called Utilities. The most useful of which are the predefined compare functions for various primitive types.

The hash functions are usually of lesser interest unless you are using hash maps, but they can be also used independently of the hash map context.

When you are working with data streams, e.g. FILE streams or any other stream (or buffer) API that uses an fwrite-compatible interface, you will find the stream copy function quite useful.

And last, but not least, if you are interested in unit testing, but don't know which testing framework to use: search no more, because we have got your back with UCX Test.
