Discussion

OT GetPointer gets a value in inObject from the item referenced by inTag.

If the object is not a valid object handle, an error is generated, OK is set to zero, and a nil pointer is returned.

If no item in the object has the given tag, a nil pointer is returned. If the FailOnNoItem option is set, an error is generated and OK is set to zero.

If an item with the given tag exists and has the type Is Pointer, the value of the requested element is returned.

If an item with the given tag exists and has any other type, OK is set to zero, and a nil pointer is returned.

Warning Under no circumstances should you attempt to store a pointer to a local or process variable in a compiled database and then try to retrieve that pointer in another process.
