i attempting allow 1 process d read memory in process a's address space, using c++/visual studio 2013, under 64-bit windows 7.

process d can thought of debugger, able read parts of particular big info construction in process a. process run using visual studio 2013 debugger, , @ breakpoint when process d looks @ a's data.

if programming @ o/s level, allow process d create copies of a's page mapping entries memory shared. there way me accomplish same result application pgm?
