sockaddr_in causing segfault?
- by Curlystraw
Working on creating a server/client system in C right now, and I'm having a little trouble with the client part. From what I've seen, I need to use sockaddr_in so I can connect to the server. However, I've been getting a segfault every time. I believe that sockaddr_in has something to do with it, as comment it and it's references later in the program fixes the segfault.
code:
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <unistd.h>
#include <netinet/in.h>
int main(int argc, char** argv)
{
int Csock;
int con;
char *data = 0;
char buf[101] = "";
struct sockaddr_in addr;
Csock = socket(AF_INET, SOCK_STREAM, 0);
addr.sin_family = AF_INET;
addr.sin_port = htons(3435);
con = connect(Csock, (struct sockaddr*) &addr, sizeof(&addr));
write(con, "Text", sizeof("Text"));
*data = read(con, buf, 100);
puts(data);
return 0;
}
sadly, I am rather new to C, so that's as much as I can figure... can anyone tell me a way to go about eliminating the segfault?
Thanks!
