Module Name:

    rtsetopt.c

Abstract:

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

    This program attempts to force all cases through the various
    optimizations in the NtSetValueKey code.

    This is a whitebox test intended force system errors (crashes)
    when run.  Returned values are not very interesting.

    rtsetopt <root of test tree>

    Example:

        rtsetopt \registry\machine\software\test

    Named key must already exist.
