“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
EAGAIN: The socket is marked as non-blocking, but the receive operation is blocked or the receive timed out. EBADF: sock is not a valid descriptor ECONNREFUSE: The remote host blocks the network connection. EFAULT: An error occurs during memory access. ...
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 is waiting...
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...
Otherwise, a value of SOCKET_ERROR is returned, and a specific error code can be retrieved by callingWSAGetLastError. Expand table Remarks Therecvfunction is used to read incoming data on connection-oriented sockets, or connectionless sockets. When using a connection-oriented protocol, the sockets ...
If an error occurs, a value of SOCKET_ERROR is returned, and a specific error code can be retrieved by calling the WSAGetLastError function. The error code WSA_IO_PENDING indicates that the overlapped operation has been successfully initiated and that completion will be indicated at a later ...
