any_tail |
Function (ROM Call 0x3B6) |
Checks whether any element in the list has some property.
any_tail is similar like all_tail, except further processing of
the list will be stopped if f returns TRUE instead
of FALSE. In other words, it returns TRUE if
and only if the callback function f returns TRUE for at least
one expression in the tail of expressions indexed by element_ptr.
any_tail is very useful to check whether any element of a list
possesses some property. Assuming the same assumptions as in the example given with
all_tail, the following call will check whether any element of
the list is a positive integer:
is_any_positive_integer = any_tail (is_positive_integer, start_ptr);
