HELPLIB.HLB  —  CRTL  bsearch  Description
    The array must first be sorted in increasing order according to
    the specified comparison function pointed to by compar.

    Two arguments are passed to the comparison function pointed to
    by compar. The two arguments point to the objects being compared.
    Depending on whether the first argument is less than, equal to,
    or greater than the second argument, the comparison function must
    return an integer less than, equal to, or greater than 0.

    It is not necessary for the comparison function (compar) to
    compare every byte in the array. Therefore, the objects in the
    array can contain arbitrary data in addition to the data being
    compared.

    Since it is declared as type pointer-to-void, the value returned
    must be cast or assigned into type pointer-to-object.
