What is the output of the program? #include #include #include #include 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,"demo_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("Example "); return 0;
