| Revision 1.1 2009/07/09 21:40:32 herscher |
| <rdar://problem/3775717> SDK: Port mDNSNetMonitor to Windows. Add a small Posix compatibility layer to the mDNSWindows platform layer. This makes it possible to centralize the implementations to functions such as if_indextoname() and inet_pton() that are made in several projects in B4W. |
