Routine Description:
|
|
|
|
This routine is a worker routine for AzScopeCreate. It does any object specific

initialization that needs to be done.

|
On entry, AzGlResource must be locked exclusively.
|
|

Arguments:
|
|
|
|
ParentGenericObject - Specifies the parent object to add the child object onto.
|
|
The reference count has been incremented on this object.
|
|
|
|
ChildGenericObject - Specifies the newly allocated child object.
|
|
The reference count has been incremented on this object.
|
|
|
|
Return Value:
|
|
|
|
NO_ERROR - The operation was successful
|
|
ERROR_NOT_ENOUGH_MEMORY - not enough memory
|
|
Other exception status codes
