The Windows version of mmap was mentioned in the message to which you replied: CreateFileMapping
In my earlier message, I mentioned how to use this from boost: Boost::Iostreams already has a mapped_file Source.
Sorry, I’ve been so busy lately I’ve been skimming messages and I still can’t keep up.
We want to avoid Windows API calls whenever possible. They usually take about 6-8 parameters and a lot of testing to get right, it takes a page of code to do something simple.
I usually shy away from iostreams. Seems like I too often hit limitations. They kind of botched the C++ streams standard in the 90’s, which is too bad, streams can be very powerful and useful when done right. Using it in rpc.cpp may still turn out to be a mistake.
Bottom line is I’d rather call an existing file copy function than make and test my own.
