CM_Get_Sibling function (cfgmgr32.h)
The CM_Get_Sibling function obtains a device instance handle to the next sibling node of a specified device node (devnode) in the local machine's device tree.
Note
In Windows Vista and later versions of Windows, the unified device property model uses the DEVPKEY_Device_Siblings property key to represent device siblings. See Retrieving Device Relations for details.
Syntax
CMAPI CONFIGRET CM_Get_Sibling(
[out] PDEVINST pdnDevInst,
[in] DEVINST dnDevInst,
[in] ULONG ulFlags
);
Parameters
[out] pdnDevInst
Caller-supplied pointer to the device instance handle to the sibling node that this function retrieves. The retrieved handle is bound to the local machine.
[in] dnDevInst
Caller-supplied device instance handle that is bound to the local machine.
[in] ulFlags
Not used, must be zero.
Return value
If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.
Remarks
To enumerate all children of a devnode in the local machine's device tree, first call CM_Get_Child to obtain a handle to the first child node, then call CM_Get_Sibling to obtain handles for the rest of the children.
For information about using device instance handles that are bound to the local machine, see CM_Get_Child.
