    Question socket connection error

    I have a server and when I try to connect to the server with a lient with connect function it returns a value of '1' I read the definition of connect, it says that upon uccessful completion it return 0 or else -1. I'm confused because what I get is neither of these. can this '1' be a error number. if so any one knows what it is or how can find out what the error is?? thank you

    OS Dependant.

    WSAGetLastError/errno.

    socket connection error

    this is my code.... nothing major just want to test my server

    Code:
    void main()
    {
       int soc, n, t, d;
       char *er;
       char recvline[51], *address= {"127.0.0.1\n"};
       struct sockaddr_in serveradd;
       //struct sockaddr SA;
    
       if(soc= socket(AF_INET, SOCK_STREAM, 0)<0)
       {
          printf("socket error\n");
       }
    
       serveradd.sin_family = AF_INET;
       serveradd.sin_port = htons(3879);
       //serveradd.sin_addr= &address;
    
       if((t = inet_pton(AF_INET, address, &serveradd.sin_addr)<=0))
       {
          printf("pton eror for %d\n", t );
       }
    
       if(d =connect(soc, (struct sockaddr *)&serveradd, sizeof(serveradd)))
    
          printf("connection error %d", d);
          //err_sys("%c", er);
    
    
    
        recv(soc, &recvline, 51, MSG_WAITALL);
       /*{
          printf("data : %c ", n);
       }*/

    "OS dependent" means...

    The value of errno is dependent on the implementation. On any UNIX variant you can use perror() to display a nice error message or any Windows system, you can get the error number by WSAGetLastError().

    Your code looks like a UNIX code, so use perror().
