Re: [Boost-users] Boost API System or Library Calls ..

Out of curiosity, wish to know if BOOST ASIO calls like -

boost::asio::read() boost::asio::transfer_all() boost::asio::write()

BOOST LEXICAL calls like - boost::lexical_caststd::string()

BOOST POSIX TIME calls like - boost::posix_time::microsec_clock::universal_time() boost::posix_time::microsec_clock::ptime()

are LIBRARY or SYSTEM calls.

How to know which calls of BOOST are SYSTEM and LIBRARY calls?

Not sure what you mean by "system" and "library" (note that a Boost function can rely on some CRT facility, which in turn might call OS API), but you always can step into a desired function and see how it's implemented.
