Module Name:

    rtvbatcr.c

Abstract:

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

    Do a batch create, VOLATILE.  (Same as rtbatcr, but creates keys volatile.)

    rtvbatcr    <KeyPath> <KeyName> <basename> <#children> <#values>

    Will attempt to create key <KeyName> as child of <KeyPath>  If
    <#children> and <#values> are 0, this is all it does.  If <KeyName>
    already exists, it will simply be used.

    Will create <#children> child cells, with names of the form
    <base>0  <base>1, etc.  Will create <#values> value entries,
    with similar names, for each created child key.  Data of
    values will be a constant string including their name.

    Example:

        rtvbatcr    \REGISTRY\MACHINE\TEST bigkey runa_ 100 100
        rtvbatcr    \REGISTRY\MACHINE\TEST\bigkey runa_1 runb_ 100 100

        Will create bigkey, give it 100 values calls runa_1 through
        runa_100, create 100 subkeys called runa_1 through runa_100
        for each of those children.

        It will then open bigkey\runa_1, and create 100 subkeys and
        100 values each for that.
