Thread: problem in non blocking code

the code keeps crashing i tried to know whish state it crashes in but didnt know

Code:

#include "inc.h"
void connect()
{
	u_long iMode = 1;
	SOCKET SITE;
	SOCKADDR_IN serverinfo;
	LPHOSTENT hostEntry;
	hostEntry = gethostbyname("www.yahoo.com");	// Specifying the server by its name;
	SITE=socket(AF_INET,//we gonna use internet
		       SOCK_STREAM,//best effor socks
			   IPPROTO_UDP);//we gonna use tcp protocol
	//next is our strctre of stuff   

	serverinfo.sin_family=AF_INET;

	serverinfo.sin_addr = *((LPIN_ADDR)*hostEntry->h_addr_list);

	serverinfo.sin_port=htons(80);

	if(ioctlsocket(SITE,FIONBIO,&iMode)==INVALID_SOCKET)//we begin using our non blocking sockets
	{
		MessageBox(NULL,"FUNCTION FAILED","FAILURE",MB_OK);
		exit(0);
	}
	connect(SITE,(SOCKADDR*)&serverinfo,sizeof serverinfo);
}
int WINAPI WinMain(IN HINSTANCE hInstance, IN HINSTANCE hPrevInstance, IN LPSTR lpCmdLine, IN int nShowCmd )
{
	connect();
}
