void cpd_memory_single_pup	(	CkHashtable_c	h,
		pup_er	p
	)

PUP a single slot of memory for the debugger.

This includes the information about the slot (like size and location), but not the allocated data itself.

PUP the entire information about the allocated memory to the debugger

Returns the content of a block of memory (i.e the user data). This request must always be at the beginning of an allocated block (not for example an object part of an array)

Perform a scan of all the memory to find all the memory that is reacheable from either the stack or the global variables.

Called before the entry method: resets all current memory for the chare receiving the message.

Called after the entry method to check if the chare that just received the message has corrupted the memory of some other chare, or some system memory.
