Using DMD 2.066 on GNU/Linux x86_64.

This is strange:

import std.stdio;
void main() {
    auto f = tmpfile();
    pragma(msg, typeof(f)); // shared(_IO_FILE)*
}

But stdio.d looks like the following:
    static File tmpfile() @safe

What is going on here?

Oh, and ldc 0.14 and gdc 4.9.1 has the same result, so it's not a backend thing at least.

You're calling `core.stdc.stdio.tmpfile`. There is no `std.stdio.tmpfile`, it's `std.stdio.File.tmpfile`.

std.stdio does this: 'public import core.stdc.stdio'.
and in core.stdc.stdio we can find this:
@trusted FILE* tmpfile();
and FILE as an alias for shared(_IO_FILE), declared in
'core.stdc.stdio' too.

to get 'File', call 'File.tmpfile()'.

Thanks.

So std.stdio.tmpfile() returns shared(_IO_FILE)* and
std.stdio.File.tmpfile() returns File.

Talk about confusing. If I want something from pure C libraries, I would use core.stdc.

dunno why std.stdio does this public import. i see no sense in it, but maybe someone with more expirience knows the answer.
