The callback comparison function.

Function <parameter>cmp_function</parameter> should accept two

parameters which will be filled by pairs of entry keys.
|
|
The comparison function must return an integer less than, equal
|
|
to, or greater than zero if the first argument is considered to
|
|
be respectively less than, equal to, or greater than the
|
|
second.
