If you are running an ordinary 32 bits MS Windows machine your process runs
in a 32 bit virtual memory space (2GB or 3GB maximum typically). The OS
prevents any other process from reading that virtual memory so there's no need
to worry about anything. On the contrary: if you want another process to be able
to read your memory you have to explicitly set up a block of shared memory.

kind regards,

Jos

Consider using a private heap.

With Windows you use CreateProcessHe ap. More info in Windows via C/C++ by Jeffrey Richter 2007.
