Routine Description:

    Provides for arbitrary communication and control between an application
    and a specific instance of a resource.

Arguments:

    hResource - Supplies a handle to the resource to be controlled.

    hNode - Supplies a handle to the node on which the resource
        control should be delivered. If this is NULL, the node where
        the resource is online is used.

    dwControlCode- Supplies the control code that defines the
        structure and action of the resource control.
        Values of dwControlCode between 0 and 0x10000000 are reserved
        for future definition and use by Microsoft. All other values
        are available for use by ISVs

    lpInBuffer- Supplies a pointer to the input buffer to be passed
        to the resource.

    nInBufferSize- Supplies the size, in bytes, of the data pointed
        to by lpInBuffer..

    lpOutBuffer- Supplies a pointer to the output buffer to be
        filled in by the resource..

    nOutBufferSize- Supplies the size, in bytes, of the available
        space pointed to by lpOutBuffer.

    lpBytesReturned - Returns the number of bytes of lpOutBuffer
        actually filled in by the resource..

    lpcbRequired - Returns the number of bytes required if OutBuffer
        is not large enough.

Return Value:

    ERROR_SUCCESS if successful

    Win32 error code otherwise

Routine Description:

    Provides for arbitrary communication and control between an application
    and a specific instance of a network interface.

Arguments:

    hNetInterface - Supplies a handle to the network interface to be controlled.

    dwControlCode- Supplies the control code that defines the
        structure and action of the network control.
        Values of dwControlCode between 0 and 0x10000000 are reserved
        for future definition and use by Microsoft. All other values
        are available for use by ISVs.

    lpInBuffer- Supplies a pointer to the input buffer to be passed
        to the network.

    nInBufferSize- Supplies the size, in bytes, of the data pointed
        to by lpInBuffer.

    lpOutBuffer- Supplies a pointer to the output buffer to be
        filled in by the network.

    nOutBufferSize- Supplies the size, in bytes, of the available
        space pointed to by lpOutBuffer.

    lpBytesReturned - Returns the number of bytes of lpOutBuffer
        actually filled in by the network.

    lpcbRequired - Returns the number of bytes required if OutBuffer
        is not large enough.


Return Value:

    ERROR_SUCCESS if successful

    Win32 error code otherwise
