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.
