BOOST_WARN_MESSAGE(predicate, message); BOOST_CHECK_MESSAGE(predicate, message); BOOST_REQUIRE_MESSAGE(predicate, message);
These tools perform exactly the same check as BOOST_<level>
tools. The only difference is that instead of generating an error/confirm
message these use the supplied one.
The first parameter is the boolean expression. The second parameter is
the message reported in case of check failure. The message argument can
be constructed of components of any type supporting the std::ostream& operator<<(std::ostream&)
.
