“recv: socket operation on non-socket” 错误信息表示尝试在一个非套接字的文件描述符上执行 recv 操作。在 Unix-like 系统中,套接字(socket)是一种特殊的文件描述符,用于网络通信。如果在一个非套接字的文件描述符(比如一个普通文件或目录)上调用 recv 函数,就会触发这个错误。 2. 常见原因 错误的文件描...

概述 在C/C++中,使用udp socket时,sendto 与 recvfrom 有不同的errno 而在高阶语言Javascript中,使用udp socket, 会将两种类型的错误通过同一个事件 error 抛出来 因此,有必要将 sendto 与 recvfrom 对应的 errno列出来
Peeks at the data present on the socket; the data is returned but not consumed, so a later receive operation sees the same data.Normal return If successful, the function returns the length, in bytes, of the message or datagram: For UDP sockets, zero length messages can be received on the...
This error code indicates one of the following: The operation issued on a non-blocking socket would have caused the thread to be suspended. The operation issued on a blocking socket did not complete within the timeout value set on the SO_RCVTIMEO socket option.Error...
Root Cause When recvfrom is used on a non-blocking socket, it returnsEAGAINerror if there are no pending data to be read. As mentioned inman 3 recvfrom: Raw ERRORS The recvfrom() function shall fail if: EAGAIN or EWOULDBLOCK The socket's file descriptor is marked O_NONBLOCK and no data...
“Peek” at the data present on the socket; the data is returned, but not consumed, so that a subsequent receive operation will see the same data. The recvmsg() call uses a msghdr structure to minimize the number of directly supplied parameters. This structure is defined in <sys/socket.h...
The socket operation is not supported. This error is returned if thedwFlagsmember of theWSAMSGstructure pointed to by thelpMsgparameter includes theMSG_PEEKcontrol flag on a non-datagram socket.
