Module Name:

    rtload.c

Abstract:

    NT level registry api test program, basic non-error paths.

    Perform an NtLoadKey call to link a hive file into the registry.

    If KeyPath is not present, it loads the hive file at
        \Registry\User\FileName

    rtload  [ <KeyPath> ] <FileName>

    Example:

        rtload \registry\user\JVert JVUser
