bsearch
The function bsearch performs a search within a sorted array, returning a pointer to the element in question or NULL.

*key refers to an object that matches an item searched within *base. This array contains num elements, each of size size.

The compare function accepts two pointers to the object within the array - which need to first be cast to the object type being examined. The function returns -1 if the first parameter should be before the second, 1 if the first parameter is after, or 0 if the object matches.
