//客户端使用上面bind过的udp sockfd 接收数据 //getMysockfd(1)函数就是 return fdUDP void socketBus::recvFrom(int* buf, int length) { int udpfd = getMysockfd(1); int ret = recvfrom(udpfd, (void *)buf, length, 0, nullptr, nullptr); } 然而在这个recvfrom会抛出 Invalid argument错误请...
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...
