NULL is a macro defined in for the null pointer.
NUL is the name of the first character in the ASCII
character set. It corresponds to a zero value. There's no
standard macro NUL in C, but some people like to define it.
The digit 0 corresponds to a value of 80, decimal.
Don't confuse the digit 0 with the value of '' (NUL)!
NULL can be defined as ((void*)0), NUL as ''.
