hello friends,
I have two program: receive.cpp and send.cpp
They re very simple, when compiling there is no error in both.
I only wanna see them to talk to each other but when run these progs,
both of them gives 10061 error. Below the codes, firstly receive.cpp:
//******************* SERVER PROG ****************
#include <winsock2.h>
#include <stdio.h>
#define DEFAULT_BUFLEN 512
#define DEFAULT_PORT "27015"
int __cdecl main() {
WSADATA wsaData;
int iResult;
SOCKET ConnectSocket;
struct sockaddr_in clientService;
char *sendbuf = "bu bir testtir.";
char recvbuf[DEFAULT_BUFLEN];
int recvbuflen = DEFAULT_BUFLEN;
iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
if (iResult != NO_ERROR) {
printf("WSAStartup failed: %d\n", iResult);
return 1;
}
ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (ConnectSocket == INVALID_SOCKET) {
printf("Error at socket(): %ld\n", WSAGetLastError() );
WSACleanup();
return 1;
}
clientService.sin_family = AF_INET;
clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );
clientService.sin_port = htons( 27015 );
iResult = connect( ConnectSocket, (SOCKADDR*) &clientService, sizeof(clientService) );
if ( iResult == SOCKET_ERROR) {
closesocket (ConnectSocket);
printf("Unable to connect to server: %ld\n", WSAGetLastError());
WSACleanup();
return 1;
}
iResult = send( ConnectSocket, sendbuf, (int)strlen(sendbuf), 0 );
if (iResult == SOCKET_ERROR) {
printf("send failed: %d\n", WSAGetLastError());
closesocket(ConnectSocket);
//WSACleanup();
return 1;
}
printf("Bytes Sent: %ld\n", iResult);
iResult = shutdown(ConnectSocket, SD_SEND);
if (iResult == SOCKET_ERROR) {
printf("shutdown failed: %d\n", WSAGetLastError());
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
do {
iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
if ( iResult > 0 )
printf("Bytes received: %d\n", iResult);
else if ( iResult == 0 )
printf("Connection closed\n");
else
printf("recv failed: %d\n", WSAGetLastError());
} while( iResult > 0 );
closesocket(ConnectSocket);
WSACleanup();
return 0;
}
and the sender.cpp
//*******************************CLIENT*********************************
#include <winsock2.h>
#include <stdio.h>
#define DEFAULT_BUFLEN 512
#define DEFAULT_PORT 27015
int main() {

SOCKET ConnectSocket;
struct sockaddr_in clientService;
int recvbuflen = DEFAULT_BUFLEN;
char *sendbuf = "Client: sending data test";
char recvbuf[DEFAULT_BUFLEN] = "";
iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
if (iResult != NO_ERROR) {
printf("WSAStartup failed with error: %d\n", iResult);
return 1;
}
ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (ConnectSocket == INVALID_SOCKET) {
printf("socket failed with error: %ld\n", WSAGetLastError());
WSACleanup();
return 1;
}
clientService.sin_family = AF_INET;
clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );
clientService.sin_port = htons( DEFAULT_PORT );
iResult = connect( ConnectSocket, (SOCKADDR*) &clientService, sizeof(clientService) );
if (iResult == SOCKET_ERROR) {
printf( "connect failed with error: %d\n", WSAGetLastError() );
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
iResult = send( ConnectSocket, sendbuf, (int)strlen(sendbuf), 0 );
if (iResult == SOCKET_ERROR) {
printf("send() failed with error: %d\n", WSAGetLastError());
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
printf("Bytes Sent: %d\n", iResult);
iResult = shutdown(ConnectSocket, SD_SEND);
if (iResult == SOCKET_ERROR) {
printf("shutdown failed with error: %d\n", WSAGetLastError());
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
do {
iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
if ( iResult > 0 )
printf("Bytes received: %d\n", iResult);
else if ( iResult == 0 )
printf("Connection closed\n");
else
printf("recv failed with error: %d\n", WSAGetLastError());
} while( iResult > 0 );
closesocket(ConnectSocket);
WSACleanup();
return 0;
}
where I do wrong?
