C++ (Cpp) nbio_connect Examples

Example #1

File: socket.c Project: miar/yaptab-linear

static foreign_t
pl_connect(term_t Socket, term_t Address)
{ int sock;
  struct sockaddr_in sockaddr;

  if ( !tcp_get_socket(Socket, &sock) ||
       !nbio_get_sockaddr(Address, &sockaddr) )
    return FALSE;

  if ( nbio_connect(sock, (struct sockaddr*)&sockaddr, sizeof(sockaddr)) == 0 )
    return TRUE;

  return FALSE;
}
