Wsasocket Vs Socket



Listen on the socket for a client. However, you can call the setsockopt API with SO_OPENTYPE option on any socket handles including an INVALID_SOCKET to change the overlapped attributes for all successive socket calls in the same thread. Shelling out to the OS simply wouldn't work for me so this code uses raw sockets in Win2k to perform an ICMP ping and get the echo reply back. Windows Service run mode + + When Squid is compiled as a Windows service, the -N command line switch is disabled, and default run mode of +Squid is no daemon (=no service) mode, so is possible to run Squid from command line +for debug purpose with all command line options available. In Winsock 1, you create an overlapped socket using the socket API, and use Win32 file I/O API ReadFile, ReadFileEx, WriteFile, WriteFileEx to perform overlapped I/O on the socket handle. Valid socket types are SOCK_STREAM to open a tcp(7) socket, SOCK_DGRAM to open a udp(7) socket, or SOCK_RAW to open a raw(7) socket to access the IP protocol directly. 把SOCKET设置为非阻塞模式,即通知系统内核:在调用WindowsSocketsAPI时,不要让线程睡眠,而应该让函数立即返回。在返回时,该函数返回一个错误代码。图所示,一个非阻塞模式套接字多次调用recv()函数的过程。前三次调用recv()函数时,内核数据还没有准备好。.

A majority of the options listed here deal with either setting or obtaining AppleTalk names. Overlapped sockets can utilize WSASend, WSASendTo, WSARecv, WSARecvFrom, andWSAIoctl for overlapped I/O operations, which allow multiple operations to be initiated and in progress simultaneously. Also it would seem strange if some sockets (created with socket()) have the overlapped attribute, but some others (created with WSASocket()) don't. The server is written in CodeBlocks IDE but im not impressed with the debugger. If you do not need the extensions, there is no real penalty to calling socket() instead, and you get a portability benefit besides. Figure 1: Graphical demonstration of a raw socket. Associate one or more file descriptors with the port. 刚才看了下代码,确认了一下,客户端创建socket调用的是socket,因为将其与一个event对象关联了起来,所以其所有操作默认变为非阻塞的。(所以send, recv之类的操作有时候会返回WSAEWOULDBLOCK). Gucci mane free download 14. You may then connect to the server with a command similar to: telnet 192. I have been using the new Socket. The first step in using raw sockets is creating the socket. WSASocket (unlike socket call) allows to create sockets that will not be inherited by child process. Nothing more and nothing less. The HTTP-compatible handshake is just to allow WebSocket connection on the same port that a webserver is running on (so the webserver can forward them), but once the connection is established, the webserver is not in the loop. When you create a socket, you’re just announcing an intention to communicate over the network. project in Visual Studio 6. A majority of the options listed here deal with either setting or obtaining AppleTalk names.
