showing bound sockets!!

int sock ;  // Socket
int c ;    //  condition
struct sockaddr_in serveraddr ;  //AF_INET
unsigned short Portnumber = 3306 ; //Port#



sock = socket(AF_INET , SOCK_STREAM , 0) ;
if ( sock == -1 )
{
    error("socket()");
}

memset(&serveraddr , 0 , sizeof serveraddr);


serveraddr.sin_family = AF_INET ;
serveraddr.sin_port   = htons(Portnumber);
serveraddr.sin_addr.s_addr  = ntohl(INADDR_ANY);

bind(sock , (struct sockaddr *)&serveraddr , sizeof serveraddr);


system("netstat -pa --tcp 2>/dev/null ");

when i run this program i cant see my bound socket in output!!
please help,
i want to write a program that listen on a specific port and each client can connect to it.
