💖 std::filesy...d_link_count(3) 💖

okay so bestie, this is the C++ Standard Libary manual page for std::filesystem::directory_entry::hard_link_count. It is lowkey a tiny little filesystem detective for hard links. ✨

---

🌸 NAME 🌸

• std::filesystem::directory_entry::hard_link_count - std::filesystem::directory_entry::hard_link_count

✨ Synopsis ✨

std::uintmax_t hard_link_count() const;
(1) (since C++17)
std::uintmax_t hard_link_count( std::error_code& ec ) const
(2) (since C++17)
noexcept;

Those are the two overloads, both (since C++17). Slay. 💅

If the number of hard links is cached in this directory_entry, returns the cached value. Otherwise, returns:

1. std::filesystem::hard_link_count(path()),
2. std::filesystem::hard_link_count(path(), ec).

💜 Parameters 💜

• ec — out-parameter for error reporting in the non-throwing overload.

🦋 Return value 🦋

The number of hard links for the referred-to filesystem object. That's it. That's the whole vibe. 🎀

🔥 Exceptions 🔥

Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails. 😭

1. Throws std::filesystem::filesystem_error on underlying OS API errors, constructed with p as the first path argument and the OS error code as the error code argument.
2. Sets a std::error_code& parameter to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur.

🌈 Example 🌈

This section is incomplete Reason: no example

Bestie, there is literally no example here. The manual page said so, not me. 💀
