Winsock error 10046

WSAEPFNOSUPPORT  -  Protocol family not supported.

Basic (Microsoft) information for 10046 a.k.a. WSAEPFNOSUPPORT

The protocol family has not been configured into the system or no implementation for it exists. This message has a slightly different meaning from WSAEAFNOSUPPORT. However, it is interchangeable in most cases, and all Windows Sockets functions that return one of these messages also specify WSAEAFNOSUPPORT.

Detailed (Berkeley) information for winsock 10046, described as "Protocol family not supported."

Berkeley description: The protocol family has not been configured into the system or no implementation for it exists.

WinSock description: Same as Berkeley. Apparently, the Windows Sockets specification left this out by oversight. The WSAEAFNOSUPPORT is the likely substitute error for this in WinSock, although its Berkeley meaning is slightly different. However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error.
