should the following code return: true or false?

if the result is false, why? I don't understand it.

It should be false. You're passing in a function pointer type, not a function type. The following would be true: boost::is_function::value Doug

if the result is false, why? I don't understand it. if the result is true, the code of boost_1_32_0/libs/type_traits/test/is_function_test.cpp line 42 expect it to be false.

could someone help me with this?

int (*)(int) is a pointer, not a function. boost::is_pointer::value should be true. Also is_function::value should be true. And is_function<:remove_pointer::type>::value should also be true. -Howard
