Hi,

I'm using file_mapping/mapped_region with Boost 1.45. My idea was to 
load the memory mapped file in read/write mode and then decrypt the
file content in-place (to avoid copying the entire file content). 
However, this will save a decrypted file :-(

Is there any way to avoid the file being saved after in-memory manipulation?
