其中,Linuxsocket编程是一种重要的编程技术,用于实现网络通信功能。 在Linuxsocket编程过程中,可能会遇到各种问题,其中之一就是
A connect request was made on an already connected socket. Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (For SOCK_STREAM sockets, the to parameter in sendto is ignored), although other implementations treat this as a legal occurrence. 连接过...
1、Socket 关闭，但是socket号并没有置-1。继续在此socket上进行send和recv，就会返回这种错误。这个错误会引发SIGPIPE信号，系统会将产生此EPIPE错误的进程杀死。所以，一般在网络程序中，首先屏蔽此消息，以免发生不及时设置socket进程被杀死的情况。2、write(..) on a socket that has been closed at the other ...
errno.86 is: Streams pipe error errno.87 is: Too many users errno.88 is: Socket operation on non-socket errno.89 is: Destination address required errno.90 is: Message too long errno.91 is: Protocol wrong type for socket errno.92 is: Protocol not available errno.93 is: Protocol not sup...
Linux网络编程socket错误码分析[参考].pdf,Linux 网络编程 socket 错误分析 socket 错误码: EINTR : 4 阻塞的操作被取消阻塞的调用打断。如设置了发送接收超时,就会遇到这种错误。 只能针对阻塞模式的 socket。读,写阻塞的 socket 时, -1 返回,错误号为 INTR 。另外,
on a locally closed socket will return EBADFEFAULT : 地址错误。EBUSY :ECONNREFUSED :1、拒绝连接。一般发生在连接建立时。拔服务器端网线测试,客户端设置keep alive时,recv较快返回0,先收到ECONNREFUSED (Connection refused)错误码,其后都是 ETI 7、MEOUT。2、an error returned from connect(), so it ...

Linux - 非阻塞socket编程处理EAGAIN错误 在linux进行非阻塞的socket接收数据时经常出现Resource temporarily unavailable,errno代码为11(EAGAIN),这是什么意思? ⇒ ⇒ ⇒ 这表明在非阻塞模式下调用了阻塞操作,在该操作没有完成就返回这个错误,这个错误不会破坏socket的同步,不用管它,下次循环接着recv就可以。对非...
