CM_Get_Sibling usage

[Jean-Luc Arnaud]

Hi all,

This question is a little bit [OT]. Nevertheless, I hope someone will be
so kind as to reply...

Working on an USB tree project, I'm using PnP Configuration Manager API
calls (CM_Locate_DevNode, CM_Get_Parent, CM_Get_Device_ID_Size and
CM_Get_Device_ID, CM_Get_Child and CM_Get_Sibling) defined as Soft
Declare Function.

All works like a charm but CM_Get_Sibling.

MSDN documentation is not really clear, and I don't understand if
CM_Get_Sibling is expected to return ALL others nodes, or only the next.

If only the next, what's the way to find the following node? Should I
recall CM_Get_Sibling with the Device instance handle CM_Get_Sibling
just returns, until no more nodes?

Thanks for your help

Hi Jean-Luc,

Give this a look to see if it helps:

It answered a number of my non-Xojo device questions.
