Arrays of Length Zero
Zero-length arrays are allowed in GNU C. They are very useful as
the last element of a structure which is really a header for a
variable-length object:
struct line {
int length;
char contents[0];
};
{
struct line *thisline = (struct line *)
malloc (sizeof (struct line) + this_length);
thisline->length = this_length;
}
In standard C, you would have to give `contents' a length of 1, which
means either you waste space or complicate the argument to `malloc'.
