Thread: 100+ errors

I am kind of new to C++ but know some. I am using Dev C++ and am getting all sorts of errors from this code.

Can someone please tell me what I am doing wrong.

Code:

#include <cstdlib>
#include < winsock.h >

WORD version = MAKEWORD(1,1);
WSADATA wsaData;
SOCKET theSocket;
char Buf[256],myBuf[256]; // Buf -for server answer and myBuf -for your commands
int nRet; // For eventual errors

int conect(char *server) { //Connects to a server using "Winsock"

// Start up Winsock
nRet=WSAStartup(version, &wsaData);
if (nRet!=0) {return(0);}

// Store information about the server
LPHOSTENT lpHostEntry;

lpHostEntry = gethostbyname(server);
if (lpHostEntry == NULL) {
WSACleanup();
return(0);
}

// Create the socket
theSocket = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
if (theSocket == INVALID_SOCKET) {
WSACleanup();
return(0);
}

SOCKADDR_IN saServer;
saServer.sin_family = AF_INET;
saServer.sin_addr = *((LPIN_ADDR)*lpHostEntry->h_addr_list);
saServer.sin_port = htons(25); // Port 25

// Connect to the server
nRet = connect(theSocket,(LPSOCKADDR)&saServer,sizeof(struct sockaddr));
if (nRet == SOCKET_ERROR) {
WSACleanup();
return(0);
}

nRet = recv(theSocket,Buf,sizeof(Buf),0);
if (nRet == SOCKET_ERROR) {
WSACleanup();
return(0);
}

if (Buf[0]=='4' || Buf[0]=='5') return(0); // Not a '220' Hello
if (Buf[0]=='2' && Buf[1]=='2' && Buf[2]=='0') {
sendmail(); // Ok to send mails
}

//Close the connection
closesocket(theSocket);


// Shutdown Winsock
WSACleanup();
}

Well you said you are getting over 100 errors. Try posting the first few. Generally when you have that many errors you either are making the same mistake over and over or you have an error that cascades into other compile time errors. But thats all a guess since you haven't given us anything to start from

As far as I can tell you never connect from main.
Also sendmail needs to be declared before connect otherwise the compiler will give you an error.
