Subject: write() udp socket
Date: Sat, 23 Jul 2011 17:29:33 +0800	[thread overview]
Message-ID: <tencent_287F494544728EDB6DA9C8ED@qq.com> (raw)

question No1:
When I call 
ssize_t write(int fd, const void *buf, size_t count);


on a nonblocking UDP socket, is the return value  always equal to 'count'?


question No2:
Can I write() a UDP socket in multiple threads without locking?


thanks
