我觉得应该是socklen_t len=sizeof(*sndaddr);。

EBADF The argument s is an invalid descriptor 我的模拟测试环境是: 前端loadrunner模拟web点击,通过后端的weblogic压自己的服务的时候发现,有时候recv会收到这个错误,意思就是这个fd已经失效了,但是有点不是很明白,所以查询下内核实现,验证下。 首先recv的实现就是调用的recvfrom: [cpp]view plaincopy /* * Rece...
The argument s is not a socket. 参数s不是一个socket套接字。 EFAULT An invalid user space address was specified for a parameter. 有参数被指定到了一个非法的用户地址空间。 EMSGSIZE The socket requires that message be sent atomically, and the size of the message to be sent made this impossi...
