Description

Ultibo Winsock interface unit

Notes:

  • All BSD/Winsock functions that accept an Address or Port expect them to be in Network order.
  • All other functions that take an Address or Port expect them to be in Host order.

Error return codes from gethostbyname() and gethostbyaddr() (when using the resolver). Note that these errors are retrieved via WSAGetLastError() and must therefore follow the rules for avoiding clashes with error numbers from specific implementations or language run-time systems. For this reason the codes are based at WSABASEERR+1001. Note also that [WSA]NO_ADDRESS is defined only for compatibility purposes.
