- values of elektra keys
In Elektra string-keys are preferred. Nevertheless, binary keys, i.e. strings
with null-characters embedded are possible.
Sometimes a key does not exist at all. When using ksLookup() you will get a null
pointer. In the C++ Binding the null pointer is wrapped in a key. Thus this is
also sometimes called NULL KEYS
Null values are binary values without content. They are the only keys that have
the size 0.
Null values are always binary values.
Empty values point to a string that only contains a null byte.
Empty values are possible for both string and binary values.
