alt Hacker NewsIn all the comments in this thread it's interesting how people confuse:
* NUL: An ASCII non-printing character with the byte value of 0
* NULL: A pointer that does not point to usable memory with the value that compiles in C to be equal to ((void *) 0).
NUL was always just an abbreviation for null: https://www.rfc-editor.org/rfc/rfc20.html#section-4
I don’t think anyone in this thread is confusing the null character with the null pointer.
