Routine Description:

This routine is a worker routine for AzOperationCreate. It does any object specific

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
