hi,
In the newsgroup someone reported a crash in gethostbyname() when the
application called it with a null parameter.
msdn says about this:
| If null is provided in the name parameter, the returned string is
| the same as the string returned by a successful gethostname
| function call.
gethostbyname does not return a string, but I think this it what they
meant to say.
I have tested gethostbyname under Win2K to do this.
Changelog:
dlls/winsock : socket.c async.c
_ws_gethostbyname() and WSAAsyncGetHostByName() when called with
a null name, should use the name returned by gethostname().
Rein.
