Hi,
I've been continuing my quest to try and use Boost for my DSP and its C++ compiler. I've been looking at Boost.Thread and it seems that it relies on one of a fixed few threading libraries to exist. I have my own native implementation of mutexes etc. and it doesn't seem like there is any easy way to plug it in without editing a lot of the boost source. Is this an issue that has been raised before?
There is an ongoing effort to standardize a variation of the boost threads lib, most recently documented here: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2447.htm Part of the motivation for the departure from the boost::threads API is to allow client-defined mutexes work with std::defined locks and condition variables. Anthony Williams has been updating the boost::threads lib on the boost main svn trunk, taking into account the standards work. This paper: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2406.html has a good rationale for the current mutex/lock and condition variable design, though a few of the names have changed since this paper was written. The opening paragraph for the Mutex Rationale in this paper is:
The overall intent of the above design is to allow user defined mutexes to work with standard defined locks, and to also allow standard defined mutexes to work with user defined locks. The standard defined mutexes and locks create mutex and lock concepts, which if followed allow for the interoperability between user defined and standard defined components (much like our existing containers and algorithms interoperate with user defined containers and algorithms).
