Are you sure that fgets changes address of destination string to NULL?
It returns NULL, but do not change destination string.

The idea of my construction is that memset initialize memory of the string
with 0.
This also represent empty string in terms of definition of string in C
language.
Consecutive call of fgets can:
a) Do nothing with string.
b) Place some data to string.

In both cases the string will be null terminated.
