As far as I know, the windows implementation does not add a terminating
NUL when the string to write is greater or equal to the given buffer
size. Otherwise it does add the NUL.
Same as for strncpy() on windows.
In my experience the windows implementation does never write behind the
given buffer, not even a terminating zero.
