Examples:
ip = bsearch (&key, base, num, width, compare)
key: Object to search for
base: Pointer to array of search data
num: Number of elements in search data
width: Width of elements in search data
compare: Function that compares two elements in search data
bsearch returns a pointer to an occurrence of key in the array pointed to
by base. If key is not found, the function returns NULL. If the array is not
in order or contains duplicate records with identical keys, the result is
unpredictable.
Performs a binary search of a sorted array
