Server not accepting connecting to client - c

Question

I'm trying to make a simple Socket program and I'm right now able to create a server socket, bind the server socket to a port and listen for incoming connections after which, when I try to start with the accepting of the connection, nothing gets printed out.
#include <netinet/in.h>
#include <sys/socket.h>
#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <unistd.h>
int main(int argc, char *argv[]){
char buffer[1024] = {0};
char *mes = "peepeepoopoo";
struct sockaddr_in server;
int addr_size = sizeof(server);
//xxxxxxxx Creating the socket xxxxxxxx
int sockfd_server = socket(AF_INET, SOCK_STREAM, 0);
int client_socket;
if(sockfd_server < 0){
printf("Socket not created\n");
return -1;
}
puts("Socket created\n");
server.sin_family = AF_INET;
server.sin_addr.s_addr = INADDR_ANY;
server.sin_port = htons(8070);
//xxxxxxxx Binding xxxxxxx
if(bind(sockfd_server,(struct sockaddr*)&server, sizeof(server)) < 0){
printf("failed to bind\n");
return -1;
}
puts("binding completed\n");
//xxxxxxxx Listening xxxxxxxx
if (listen(sockfd_server,3) < 0)
{
printf("Listening error\n");
}
puts("Listening\n");
// none of the statements prints, almost like its frozen.
int new_Socket = accept(sockfd_server, (struct sockaddr*)&server, (socklen_t*)&addr_size);
if(new_Socket < 0){
printf("could not accept socker\n");
return -1;
}
puts("accepted\n");
int val = read(new_Socket,buffer, 1024);
printf("%s\n",buffer);
send(new_Socket, mes, strlen(mes), 0);
return 0;
}
What do I do to fix this?

Answer 1

accept
If no pending connections are present on the queue, and the socket is not marked as nonblocking, accept() blocks the caller until a connection is present.
Question: Do you connect a client to your server?
addr_size is declared as int, yet passed as an argument while casting it to socklen_t. Can you guarantee that sizeof(int) == sizeof(socklen_t)?
You read into buffer but do not null-terminate it before passing it to printf with the format specifier %s.
