调用getpeername而不是getsockopt。如果ENOTCONN失败,则连接失败,然后必须使用SO_ERROR调用getsockopt以获取套接字的挂起错误。 调用长度为0的read。如果read失败,则connect失败,而来自read的errno指示连接失败的原因。当连接成功时,read应该再次返回0. 调用connect。它应该会失败,如果error是EISCONN,则套接字已经连接,第一...

SO_ERROR vs. errno For getting socket syscall (like recv) error, which is better (at performance level) ? Use the plain old errno Or use SO_ERROR as getsockopt() optname ? I think errno (defined to __error() on my ... c
