[PATCH v8 0/1] MR4940: bug #56065 - add stub for GetAnycastIpAddressTable()

[Rastislav Stanik (＠rastos)]

for details see https://bugs.winehq.org/show_bug.cgi?id=56065
This change adds an implementation of Win32 API function GetAnycastIpAddressTable() that is used by Adoptium OpenJDK 21 and later to initialize Secure Random Generator. This implementation does not return real information, it just says "no entries found".
