Socket error WSAE*

All Windows Sockets error constants are biased by WSABASEERR from the "normal"

Windows Sockets definitions of regular Microsoft C error constants

`WSAEBADF = GlobalSock.WSAEBADF;`
`WSAEACCES = GlobalSock.WSAEACCES;`
`WSAEFAULT = GlobalSock.WSAEFAULT;`
`WSAEINVAL = GlobalSock.WSAEINVAL;`
`WSAEMFILE = GlobalSock.WSAEMFILE;`

Windows Sockets definitions of regular Berkeley error constants
`WSAEWOULDBLOCK = GlobalSock.WSAEWOULDBLOCK;`
`WSAEINPROGRESS = GlobalSock.WSAEINPROGRESS;`
`WSAEALREADY = GlobalSock.WSAEALREADY;`
`WSAENOTSOCK = GlobalSock.WSAENOTSOCK;`
`WSAEDESTADDRREQ = GlobalSock.WSAEDESTADDRREQ;`
`WSAEMSGSIZE = GlobalSock.WSAEMSGSIZE;`
`WSAEPROTOTYPE = GlobalSock.WSAEPROTOTYPE;`
`WSAENOPROTOOPT = GlobalSock.WSAENOPROTOOPT;`
`WSAEPROTONOSUPPORT = GlobalSock.WSAEPROTONOSUPPORT;`
`WSAESOCKTNOSUPPORT = GlobalSock.WSAESOCKTNOSUPPORT;`
`WSAEOPNOTSUPP = GlobalSock.WSAEOPNOTSUPP;`

Extended Windows Sockets error constant definitions
`WSASYSNOTREADY = GlobalSock.WSASYSNOTREADY;`
`WSAVERNOTSUPPORTED = GlobalSock.WSAVERNOTSUPPORTED;`
`WSANOTINITIALISED = GlobalSock.WSANOTINITIALISED;`

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.

Authoritative Answer: Host not found
`WSAHOST_NOT_FOUND = GlobalSock.WSAHOST_NOT_FOUND;`
`HOST_NOT_FOUND = GlobalSock.HOST_NOT_FOUND;`

Non-Authoritative: Host not found, or SERVERFAIL
`WSATRY_AGAIN = GlobalSock.WSATRY_AGAIN;`
`TRY_AGAIN = GlobalSock.TRY_AGAIN;`

Non recoverable errors, FORMERR, REFUSED, NOTIMP
`WSANO_RECOVERY = GlobalSock.WSANO_RECOVERY;`
`NO_RECOVERY = GlobalSock.NO_RECOVERY;`

Valid name, no data record of requested type
`WSANO_DATA = GlobalSock.WSANO_DATA;`
`NO_DATA = GlobalSock.NO_DATA;`

no address, look for MX record
`WSANO_ADDRESS = GlobalSock.WSANO_ADDRESS;`
`NO_ADDRESS = GlobalSock.NO_ADDRESS;`

Windows Sockets errors redefined as regular Berkeley error constants. These are commented out in Windows NT to avoid conflicts with errno.h. Use the WSA constants instead.
