udp协议下sendto与recvfrom函数对应的errno 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,以便在error中进行区分 var code = “a9fb4b37-0ec1-447...
65,527 bytes (for a UDP socket) or 32,767 bytes (for a RAW socket). The send buffer size defined by theSO_SNDBUFoption. flags Set to 0 the following value: MSG_DONTROUTE TheSO_DONTROUTEoption is turned on for the duration of the operation. This is usually used only by diagnostic or...
(PHP 5, PHP 7, PHP 8) stream_socket_sendto— Sends a message to a socket, whether it is connected or not 说明 stream_socket_sendto( resource $socket, string $data, int $flags = 0, string $address = ""): int|false Sends the specified data through the socket. ...
Blocking sockets will block until the requested number of bytes are sent. Since a non-blockingSocketcompletes immediately, it might not send all of the bytes requested in a single operation. It is your applications responsibility to keep track of the number of bytes sent and to r...
in which case the socket is treated as a nonoverlapped socket. A completion indication will occur (invoking the completion routine or setting of an event object) when the supplied buffers have been consumed by the transport. If the operation does not complete immediately, the final completion sta...
Nonoverlapped sockets: The socket is marked as nonblocking and the send operation cannot be completed immediately. WSANOTINITIALISED A successful WSAStartup call must occur before using this function. WSA_IO_PENDING An overlapped operation was successfully initiated and completion will be indicated at...

The send(), sendmsg(), and sendto() system calls will fail if: [EACCES] The SO_BROADCAST option is not set on the socket and a broadcast address is given as the destination. [EAGAIN] The socket is marked non-blocking and the requested operation would block. [EBADF] An invalid descript...
