|
|
Network - Supplies the network to be controlled.
|
|
|
|
HostNode - Supplies the host node on which the resource control should
|
|
be delivered. If this is NULL, the local node is used. Not honored!
|
|
|
|
ControlCode- Supplies the control code that defines the
|
|
structure and action of the resource control.
|
|
Values of ControlCode between 0 and 0x10000000 are reserved
|
|
for future definition and use by Microsoft. All other values
|
|
are available for use by ISVs
|
|
|
|
InBuffer- Supplies a pointer to the input buffer to be passed
|
|
to the resource.
|
|
|
|
InBufferSize- Supplies the size, in bytes, of the data pointed
|
|
to by lpInBuffer..
|
|
|
|
OutBuffer- Supplies a pointer to the output buffer to be
|
|
filled in by the resource..
|
|
|
|
OutBufferSize- Supplies the size, in bytes, of the available
|
|
space pointed to by lpOutBuffer.
|
|
|
|
BytesReturned - Returns the number of bytes of lpOutBuffer
|
|
actually filled in by the resource..
|
|
|
|
Required - Returns the number of bytes if the OutBuffer is not big
|
|
enough.
|

Return Value:
|

ERROR_SUCCESS if successful
