Howto convert IPv6 from WTSClientAddress to string?

[Guest Remko]

With WTSQuerySessionInfo you can query the client address by passing in the

WTSClientAddress constant. This returns a _WTS_CLIENT_ADDRESS structure:

typedef struct _WTS_CLIENT_ADDRESS { DWORD AddressFamily; BYTE Address[20];

} WTS_CLIENT_ADDRESS, *PWTS_CLIENT_ADDRESS;

 

I tried using RtlIpv6AddressToString but that doesn't return a valid

address. Please suggest how to convert.

Hello,

There is no API for this. You have to manually format the IPV6 address into

a string. Each octet takes 2 bytes so examining the Address member in

WTS_CLIENT_ADDRESS you should be able to walk the array to assemble the IPV6

address.
