openServiceSockets if statement always true

[pwinkler-ds]

Here num_sockets is always 0 why is the check done then?

int mDNS::openServiceSockets(int *sockets, int max_sockets) {
  // When receiving, each socket can receive data from all network interfaces
  // Thus we only need to open one socket for each address family
  int num_sockets = 0;

  // Call the client socket function to enumerate and get local addresses,
  // but not open the actual sockets
  openClientSockets(0, 0, 0);

  if (num_sockets < max_sockets) {
    sockaddr_in sock_addr{};
    sock_addr.sin_family = AF_INET;int mDNS::openServiceSockets(int *sockets, int max_sockets) {
