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.
hHostNode - 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.
