### VDHArmContextHook - Purpose

Context Issues: This function can be called in the task or interrupt context.

DOS Session Terminations: Any context hooks allocated in the context of the terminating DOS session are deallocated by the DOS Session Manager.

Notes: After calling this routine, the caller is guaranteed that the context hook will be executed before any user-space code (global context) or any V86 code in the specified DOS session (local context).
