Error using Winsock

[indianhits]

Hello, when i try to compile a winsock code i get following error

Here is the full error:
||=== client, Debug ===|
C:\Documents and Settings\HarishAdmin\My Documents\harish\main.c||In function 'main':|
C:\Documents and Settings\HarishAdmin\My Documents\harish\main.c|24|error: 'sockaddr_in' undeclared (first use in this function)|

||=== Build finished: 5 errors, 2 warnings ===|


i linked the libws2_32.a and even the libwsock32.a
but still it keeps showing the problem
and yes the code is correct i check it in my MSVC
please help me.Thanks!

You are getting a compiler error; not a linker error. Please check that you have used correct header.

Also note that this issue is not related to Code::Blocks. Please search appropriate forum in internet.

Here is the full code it works in MSVC

Code

#include <stdio.h>
#include <winsock2.h>
#include <windows.h>

int main()
{
        // Initialize Winsock
        WSADATA wsaData;

        if (WSAStartup(MAKEWORD(2,2), &wsaData) != NO_ERROR)
                printf("Error at WSAStartup()\n");

        // Create a SOCKET for connecting to server
        SOCKET ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
        if (ConnectSocket == INVALID_SOCKET) 
        {
                printf("Error at socket(): %ld\n", WSAGetLastError());
                WSACleanup();
                return 0;
        }

        // The sockaddr_in structure
        sockaddr_in client; 
        client.sin_family = AF_INET;
        client.sin_addr.s_addr = inet_addr("192.168.176.1");
        client.sin_port = htons(80);

        // Connect to server.
        if (connect(ConnectSocket, (SOCKADDR*) &client, sizeof(client)) == SOCKET_ERROR) 
        {
                printf("Failed to connect.\n" );
                WSACleanup();
                return 0;
        }

        printf("Connected to server.\n");

        char buffer[1024];
        char filename[512] = "/";
        char hostname[512] = "192.168.176.1";

        sprintf(buffer, "GET %s HTTP/1.1\r\n", filename);
        sprintf(buffer, "%sHost: %s\r\n", buffer, hostname);

        printf("%s\n", buffer);

        send(ConnectSocket, buffer, strlen(buffer), 0);

        int y;
        while(y = recv(ConnectSocket, buffer, 512, 0))
        {
                printf("%s", buffer);
        }

        WSACleanup();
        return 0;
}

You need to change line 24 to -

        struct sockaddr_in client;

Note the item in Bold-Red colour.

GCC being more standards compliant doesn't allow original code to be compiled.


Also note that as this is not an issue with Code::Blocks, similar future posts may get locked. Please search internet first.
