sendto bug

Fri Mar 29 14:54:00 GMT 2002

Actually the Single UNIX Specification says:
	If the socket is connectionless-mode, the message will be sent to
	the address specified by dest_addr. If the socket is
	connection-mode, dest_addr is ignored.
And since sendto calls either WSASendTo or winsock 1 sendTo that state:
	Even if the connectionless socket has been previously connected
	using the connect function to a specific address, lpTo overrides
	the destination address for that particular datagram only. On a
	connection-oriented socket, the lpTo and iToLen parameters are
	ignored; in this case, the WSASendTo is equivalent to WSASend.
Therefore there should be no harm in passing in the NULL value to sendto.

Quoting cgf:
I don't see anything in the linux man page or the Single UNIX
Specification which indicates that the "to" address can be NULL.
