  /*
   * bsearch - binary search an array of elements
   * @key: pointer to item being searched for
   * @base: pointer to first element to search
   * @num: number of elements
   * @size: size of each element
   * @cmp: pointer to comparison function
   *
   * This function does a binary search on the given array.  The
   * contents of the array should already be in ascending sorted order
   * under the provided comparison function.
   *
   * Note that the key need not have the same type as the elements in
   * the array, e.g. key could be a string and the comparison function
   * could compare the string with the struct's name field.  However, if
   * the key and elements in the array are of the same type, you can use
   * the same comparison function for both sort() and bsearch().
