## 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.
