> This is a very popular confusion. In a situation where the type you're dealing with is "pointer" -- for example, in an argument list of a function that has a prototype -- the token 0 means "the null pointer". It does not mean the integer zero. Its length is that of a pointer, which may be different from that of the plain integer 0. But you never write 0L for a null pointer, only 0.
Actually, 0L is equally valid as a null pointer.
