DESCRIPTION

     The prop_array_util family of functions are provided to make getting and
     setting values in arrays more convenient in some applications.

     The getters check the type of the returned object and, in some cases,
     also ensure that the returned value is within the range implied by the
     getter's value type.

     The setters and adders handle object creation and release for the caller.

     If the sizep argument to prop_array_get_data() is not NULL, then it will
     be set to the size of the returned data.

     The prop_array_get_data(), prop_array_set_data_nocopy(), and
     prop_array_add_data_nocopy() do not copy the data that is set or
     returned.  See prop_data(3) for more information.

     The prop_array_get_string(), prop_array_set_string_nocopy(), and
     prop_array_add_string_nocopy() do not copy the string that is set or
     returned.  See prop_string(3) for more information.  The
     prop_array_set_and_rel() and prop_array_add_and_rel() functions add the
     object to the array and release it.  The object is always released, even
     if adding it to the array fails.


RETURN VALUES

     The prop_array_util getter functions return true if the object exists in
     the array and the value is in-range, or false otherwise.

     The prop_array_util setter and adder functions return true if creating
     the object and storing it in the array is successful, or false otherwise.
