Retreive Use Logged in Session

[jbsys]

Hi;
Using VC++, and assuming we are talking about Win32 based windows network servers, is there a way in C++ to retrieve the currently logged on user's session id? It can be done in UNIX on the HP-UX, I'm wondering if it can be done on a windows network server. If so, how? Please provide example code if possible.

P.S. This question is in no way associated with an internet website IIS login session. Strictly deals with a user being logged onto a network server.

Thanks

Try the environment variable USERNAME. Works for 2000 and XP.

Thanks.
yes that works for the user's username, I'm trying find out if there is a way to retrieve the internal session id.

Just wondering...

What do you mean "network server"? Telnet, SSH? Windows usually are file servers. What do you use that "session ID" for in your project? Are you shure, there are such things in Windows like "sessions" and "session ID's" at all?

The logged user's session Id in a Win32 environment is actually part of a process's token. If you have the process ID, you should be able to get the process's session id. On the HP-UX, you have getpid() and getsid(). getpid() returns the process id and getsid() returns the user's session id. There is a similar getpid() function for the Win32 environment by including the process.h header into a c++ program. However, there is no easy equivalent for the getsid(). Apparently, the session id of the process's token is attainable, I'm looking for an easy way to obtain, and place the values into an environment variable, the PID and SID of the currently running process. These ID's will be used to create unique file names.

GetTempFileName() could be used to create unique file names.

I'll check that out and let you know.
