ProcessIdToSessionId missing in KERNEL32

[Silvan Scherrer]

While starting a Java app i get the following mesasage:
The application has called the non-existing api KERNEL32->ProcessIdToSessionId? (loaded by JUNIPEREXT.EXE)

And which java app is that?

[Silvan Scherrer]

It's a cirtix based Terminalsession app. I can give you access to it of course.

Ok, we will look into that soon.

proposed fix for that in src/kernel32/process.cpp:

/***********************************************************************
 * ProcessIdToSessionId   (KERNEL32.@)
 * This function is available on Terminal Server 4SP4 and Windows 2000
 */
BOOL WINAPI ProcessIdToSessionId( DWORD procid, DWORD *sessionid_ptr )
{
    /* According to MSDN, if the calling process is not in a terminal
     * services environment, then the sessionid returned is zero.
     */
    *sessionid_ptr = 0;
    return TRUE;
}

That patch should definitely solve the unresolved API error. But judging from MSDN comments and from the app you need it for (TerminalSession?) I suppose they want a real session ID in order to do something with it. The rest depends how they handle the NULL situation: can they work w/o a session ID or not.
