The simple answer is: no, there is no platform independent way. Even keeping the data only in memory, it will still risk being swapped out to disk by the virtual memory manager.

On Windows, you can use VirtualLock() to force the memory to stay in RAM. You can also use CryptProtectMemory() to prevent other processes from reading it.

On POSIX systems (e.g. BSD, Linux) you can use mlock() to lock memory in RAM.
