The header <boost/current_function.hpp> defines a single macro, BOOST_CURRENT_FUNCTION, similar to the C99 predefined identifier __func__.

BOOST_CURRENT_FUNCTION expands to a string literal containing the (fully qualified, if possible) name of the enclosing function. If there is no enclosing function, the behavior is undefined.

Some compilers do not provide a way to obtain the name of the current enclosing function. On such compilers, BOOST_CURRENT_FUNCTION expands to "(unknown)".
