Ndak Belajar Winsock!

Recommended Posts


awat la dapat error yg ampeh ni.x reti ndak solve.

2 winsocktutorial.c

winsock32.h: No such file or directory

camna ndak atasi?

ni code dia

#include <windows.h>
#include <winsock32.h>
#include <stdio.h>

#define NETWORK_ERROR -1
#define NETWORK_OK     0

void ReportError(int, const char *);

int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmd, int nShow) {
	WORD sockVersion;
	WSADATA wsaData;
	int nret;

	sockVersion = MAKEWORD(1, 1);			// We'd like Winsock version 1.1

	// We begin by initializing Winsock
	WSAStartup(sockVersion, &wsaData);

	// Next, create the listening socket
	SOCKET listeningSocket;

	listeningSocket = socket(AF_INET,		// Go over TCP/IP
			         SOCK_STREAM,   	// This is a stream-oriented socket
				 IPPROTO_TCP);		// Use TCP rather than UDP

	if (listeningSocket == INVALID_SOCKET) {
		nret = WSAGetLastError();		// Get a more detailed error
		ReportError(nret, "socket()");		// Report the error with our custom function

		WSACleanup();				// Shutdown Winsock
		return NETWORK_ERROR;			// Return an error value

	// Use a SOCKADDR_IN struct to fill in address information
	SOCKADDR_IN serverInfo;

	serverInfo.sin_family = AF_INET;
	serverInfo.sin_addr.s_addr = INADDR_ANY;	// Since this socket is listening for connections,
							// any local address will do
	serverInfo.sin_port = htons(8888);		// Convert integer 8888 to network-byte order
							// and insert into the port field

	// Bind the socket to our local server address
	nret = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));

	if (nret == SOCKET_ERROR) {
		nret = WSAGetLastError();
		ReportError(nret, "bind()");


	// Make the socket listen
	nret = listen(listeningSocket, 10);		// Up to 10 connections may wait at any
							// one time to be accept()'ed

	if (nret == SOCKET_ERROR) {
		nret = WSAGetLastError();
		ReportError(nret, "listen()");


	// Wait for a client
	SOCKET theClient;

	theClient = accept(listeningSocket,
			   NULL,			// Optionally, address of a SOCKADDR_IN struct
			   NULL);			// Optionally, address of variable containing
							// sizeof ( struct SOCKADDR_IN )

	if (theClient == INVALID_SOCKET) {
		nret = WSAGetLastError();
		ReportError(nret, "accept()");


	// Send and receive from the client, and finally,

	// Shutdown Winsock
	return NETWORK_OK;

void ReportError(int errorCode, const char *whichFunc) {
   char errorMsg[92];					// Declare a buffer to hold
							// the generated error message

   ZeroMemory(errorMsg, 92);				// Automatically NULL-terminate the string

   // The following line copies the phrase, whichFunc string, and integer errorCode into the buffer
   sprintf(errorMsg, "Call to %s returned error %d!", (char *)whichFunc, errorCode);

   MessageBox(NULL, errorMsg, "socketIndication", MB_OK);

macam dah deprecated jer sample codes kat atas tu. kalau betul nak buat socket programming kat windows, awak kena ikut latest standard la.

pasal winsock, the best reference ada kat sini http://msdn2.microsoft.com/en-us/library/m...632(VS.85).aspx

tapi kena download visual c++ 2008 express edition (free) and platform sdk (free), optionally codeblocks ide sebab ide visual c++ tu memang berat. i tak suka :)
