[Boost-users] Boost.Thread locking across two functions

Hello!

I am using a library which itself internally does not use any thread
sync mechanisms but it provides callback functions
lib_lock() and lib_unlock() which I can specify if the lib is used in
multithread environment.
lib_lock() would get called before critical segment and after it
lib_unlock() would get called.

I read Boost.Thread documentation and I understand that lock concept is
not thread-safe itself and should be used only at block scope.
This makes me think that I have no way to use locking provided by Boost
to acquire a lock in
lib_lock() function and release it in lib_unlock()? But I am not sure.

Do you have any suggestions if this can be done using Boost?

Thanks!
