elektra-values(7) -- 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

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

Empty values point to a string that only contains a null byte.

Empty values are possible for both string and binary values.
