-// This header file defines the entire interface between libc and an external
-// user of libc. It's purpose is to allow an external user the ability to get
-// notification whenever libc accesses the data provided to it by a client or
-// caller of an API. The initial purpose of this sort of notification is for
-// an address sanitizer, containing additional meta-data about memory related
-// bounds and accessibility, to perform such checks and respond appropriately
-// such as failing with a diagnostic message. There is only a single hook for
-// each of the (presently) four entrypoints and these hooks are initially all
-// empty. All of the entrypoints must be set in a single call and the opera-
-// tion is destructive to any hook already registered but chaining is allowed
-// but will have to managed by the setter which returns the current earlier
-// set of hooks which can then be used by the setter to pre or post chain to
-// as desired.
