Re: [Boost-users] [type_traits] data pointers and function pointers

It is difficult in some places in the type_traits documentation to tell when the documentation mentions "pointer" whether this refers to data pointers, function pointers, member data pointers, and/or member function pointers. I assume that if the documentation just refers to "pointer" that it should mean all of the above. But here goes:

1) Does the 'remove_pointer' refer to all of the above ? The examples are only for a single one of the above, a data pointer.

It excludes pointers to members, because the result would not be a valid type.

Could this please be added to the documentation ? I will make the suggestion on Trac.

2) The 'is_pointer' doc does say it excludes pointer to members by which I assume this means both member data and member functions. Is there any way to tell whether a pointer is a function pointer or a data pointer by using type_traits since 'is_pointer' includes both ?

is_function::value

Excellent ! Thanks ! Perhaps an is_object_pointer ( data pointer ) and is_function_pointer would be nice in type_traits, as a convenience, as this completes the four specific pointer types along with the already existing is_member_function_pointer and is_member_object_pointer. I'll make the suggestion on Trac.
