- ## BOOST_CURRENT_FUNCTION
- 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 unspecified.
- Some compilers do not provide a way to obtain the name of the current enclosing
- function. On such compilers, or when the macro `BOOST_DISABLE_CURRENT_FUNCTION`
- is defined, `BOOST_CURRENT_FUNCTION` expands to `"(unknown)"`.
- `BOOST_DISABLE_CURRENT_FUNCTION` addresses a use case in which the programmer
- wishes to eliminate the string literals produced by `BOOST_CURRENT_FUNCTION` from
- the final executable for security reasons.
