Module Name:

newdel.cxx

Abstract:
|
|||
|
|
|
|||
|
|
This module implements the C++ new and delete operators for
|
|||
|
|
the Setup-Loader environment. In other environments, the utilities
|
|||
|
|
use the standard C++ new and delete.
|
|||
|
|
|
|||
|
|
Environment:
|
|||
|
|
|
|||
|
|
ULIB, User Mode
