/*++
Routine Description:
This routine dynamically retrieves the entrypoint to a Windows 2000 (and
later) Configuration Manager (CM) API that can be used to detect whether
there are presently any device installations in-progress. If this API is
not available (it may be obsoleted on future releases of the OS), then the
API assumes there are no device installations in progress. This is OK,
because future versions of the OS will suppress auto-run when "Found New
Hardware" wizard is up, thus eliminating the need for apps to do their own
checking.
Arguments:
none
Return Value:
If there is presently a device installation in progress, the return value
is TRUE.
If there is not presently a device installation in progress, or we were
unsuccessful in retrieving the necessary Configuration Manager API, then
the return value is FALSE.
