It depends on the specs of "length" :-)

What do you mean with specs?

How it is defined to behave in the documentation (i.e., whether the documentation says "if you call length with as argument a nil pointer, the result is defined to be 0", or "the behaviour of length with as argument a nil pointer is undefined", or simply doesn't mention it at all).

btw i forgot to mention, i tested on winxp.
In Delphi the result is 0, and no error.

Delphi obviously is a lot more tolerant to bad programming than we are... A pchar which is nil is not an empty string, but an invalid pointer. It's like assuming that a nil pointer to a longint is the same as a pointer to the value 0 or so.
