boost::filesystem::file_size returns 0 for symbolic links on Windows

[TorstenHauska]

Hello,

when executing boost::filesystem::file_size on a symbolic link on Windows the functions returns a size of 0. The same call on Linux returns the size of the file the symbolic link is pointing to. I'm unsure what the correct outcome should be but I would vote for the Linux version.

I used boost version 1.85.0 on both systems.

Here the code of a simple command line tool to reproduce the problem:

#include <iostream>

#include <boost/filesystem.hpp>

int main(int argc, char *argv[])
{
    if (argc < 2)
        return -1;

    std::uint64_t size = boost::filesystem::file_size(argv[1]);

    std::cout << size << '\n';

    return 0;
}

Kind regards,
Torsten Hauska
