I am very sorry if this topic is unrelated to the topics covered by this
mailing list.

While developing a small project which consists of exporting a blockv
device via network (if you are curious: https://github.com/raphaelsc/blockv),
there was the need to lock a range of a shared resource, such as a file. I
searched for resources coming from C++ standard library and boost library,
but I wasn't able to find anything that would fit my needs. Am I missing
something?

Anyway, I ended up implementing my own range locking mechanism. The
implementation is quite simple, feel free to look it at:
https://github.com/raphaelsc/byte-range-lock-cpp/blob/master/range_lock.hh
(I made my best effort to document it well)

Is there any chance that something like range_lock will be made available
in the next versions of boost library?

Thank you very much for reading this,
