user.c
This module implements the "user" command of the W3 Server
debugger extension DLL.
The "user" command dumps the info pertaining to a specific user.
There is one parameter to this command. If this parameter is
positive, it is assumed to be the address of a USER_DATA structure
for a specific user. If the parameter is negative, its absolute
value is assumed to be a user ID. If no parameter is given, info
for all connected users is dumped.

NAME: user
SYNOPSIS: Displays the info for a specific user.
ENTRY: hCurrentProcess - Handle to the current process.
hCurrentThread - Handle to the current thread.
dwCurrentPc - The current program counter
(EIP for x86, FIR for MIPS).
lpExtensionApis - Points to a structure containing
pointers to the debugger functions
that the command may invoke.
lpArgumentString - Points to any arguments passed
to the command.
NOTES: The argument string must contain either the address of
a USER_DATA structure (if positive) or a user ID (if
negative).
