[boost] feature request: file lock

11 Jun 2004

      Hi,

I propose the inclussion of the following set of private members to the
boost::filesystem::fstream class:

private:
	void do_lock();
	bool do_trylock();
	bool do_timedlock(const xtime& xt);
	void do_unlock();
	void do_lock(cv_state& state);
	void do_unlock(cv_state& state);

this will enable additional classes:
namespace boost { namespace filesystem {
	class scooped_lock;
	class scooped_try_lock;
	class scoped_timed_lock;
} }
with an interface like boost::thread::scooped_lock and sccoped_try_lock.

What do you think about this? If you want to proceed and need help, please
let me know, I can provide an implementation for Windows (NT and above) and
posix (I'm currently working on this functionality).

Cordially,

Jordi Vilar
