Linux Debugging Interview Question:

What is the output of the program no 13?

#include<stdio.h>
#include<sys/types.h>
#include<sys/un.h>
#include<sys/socket.h>

int main()
{
struct sockaddr_un add_server, add_client;
int fd_server, fd_client;
int len;
char ch;
fd_server = socket(AF_UNIX,SOCK_STREAM,0);
if(fd_server == -1)
perror("socket");
add_server.sun_family = AF_UNIX;
strcpy(add_server.sun_path,"san_sock");
if( bind(fd_server,(struct sockaddr*)&add_server,sizeof(add_server)) != 0)
perror("bind");
if( listen(fd_server,3) != 0)
perror("listen");
len = sizeof(add_client);
fd_client = accept(fd_server,(struct sockaddr*)&add_client,&len);
printf("googlen");
return 0;
}

a) the program will print the string "google"
b) the process will remain block
c) segmentation fault
d) none of the mentioned
