Hi !
If I will make

char* pHugeMemory = (char*)malloc( huge_number_of_bytes );

in some place of my program, and after some time my program will jump
to other processing place, that won't reference pHugeMemory location,
then if physical memory storage is full, I  suppose Windows, will
discard lots of RAM memory pages to some swap place on my Hard Disk
drive... right ?
Now, if after some time I will refernce pHugeMemory, for reading, for
example, then Windows will discard ( may be ) , something else and for
sure will load all pHugeMemory  back to physical memory.
Now Question:

Is there some win32  functions that could make me aware when my program
references pHugeMemory  memory location ? I mean to make me aware of
when someone tries to read or write that location ?

More exactly :
 that  memory allocation is one XXX.DLL ( that is : allocated in
function exported from DLL ) that is shared among more then one
process.
I would like to make aware all other processes ( that have loaded
XXX.DLL ) when one process tries to read/write  any located memory (
pHugeMemory ) from a function  exported from that XXX.DLL.

Any suggenstions are welcome.
Thank you in advance.

PS:
 I that don't make sense I will more accurate next time ;)
