Problem:

Edition of Specification (Year): 2004

Defect code :  3. Clarification required

Standard states: "The tdelete() function shall return a pointer to the parent 
of the deleted node, or a null pointer if the node is not found." But there is 
no information which value should be returned when deleting the root node.

Possible incorrect behavior of applications that use tdelete() function if 
developers estimates about the returned value do not correspond to 
implementation behavior.

It's proposed to clarify this place in the Standard and define the returned 
value of the function when deleting the root node.

Action:

 No suggestions.
