Правильно ли я понял идею асинхронных сокетов?
По идее я что то упустил если не сложно подскажите //////////////////////////////////////////////////////////////////
#include <windows.h>
#include <winsock.h>
#define WM_SELECT WM_USER+1
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
SOCKET sock;
SOCKET newsock[1000];
WSADATA ws;
DWORD currentsock;
WORD WSAEvent;
sockaddr_in addr;
MSG msg;
if(WSAStartup(0x101,&ws))
{MessageBox(NULL,"WSAStartup Error",NULL,NULL);return 0;} sock=socket(AF_INET,SOCK_STREAM,0);
addr.sin_addr.s_addr=INADDR_ANY;
addr.sin_family=AF_INET;
addr.sin_port=htons(8888); if(bind(sock,(sockaddr*)&addr,sizeof(addr)))
{MessageBox(NULL,"this port is used",NULL,NULL);return 0;}
if(listen(sock,5))
{MessageBox(NULL,"listen Error",NULL,NULL);return 0;}
WSAAsyncSelect(sock,(HWND__ *)hInstance,WM_SELECT,FD_ACCEPT|FD_READ|FD_CLOSE); while(GetMessage(&msg,NULL,NULL,NULL))
{
switch (msg.message)
{
case WM_SELECT:
MessageBox(NULL,"WM_SELECT",NULL,NULL);
currentsock=msg.wParam;
WSAEvent=WSAGETSELECTEVENT(msg.lParam);
switch(WSAEvent)
{
case FD_CLOSE:
MessageBox(NULL,"FD_CLOSE",NULL,NULL);
shutdown(newsock[currentsock],1);
closesocket(newsock[currentsock]);
break;
case FD_READ:
MessageBox(NULL,"FD_READ",NULL,NULL);
break;
case FD_ACCEPT:
MessageBox(NULL,"FD_ACCEPT",NULL,NULL);
newsock[currentsock]=accept(sock,NULL,NULL);
break;
}
break;
}
}
WSACleanup();
return 0;
}
