std::experi...em::is_fifo(3)

💅 std::experi...em::is_fifo(3) 💅

okay so bestie, welcome to the C++ Standard Libary manual — yes, that's literally how the manual name is spelled here, and no, we are not fixing it. This page is all about std::experimental::filesystem::is_fifo, and it's giving "tiny little check, very important vibes." 🫶

---

✨ NAME ✨

std::experimental::filesystem::is_fifo — and yep, the name again for good measure: std::experimental::filesystem::is_fifo. 💖

---

🌸 Synopsis 🌸

Defined in header <experimental/filesystem>
bool is_fifo( file_status s );                 (1) (filesystem TS)
bool is_fifo( const path& p );                 (2) (filesystem TS)
bool is_fifo( const path& p, error_code& ec ); (3) (filesystem TS)

So like, this whole thing checks if the given file status or path corresponds to a FIFO or pipe file. That's the whole assignment. 💅

1. Equivalent to s.type() == file_type::fifo.
2. Equivalent to is_fifo(status(p)).
3. Equivalent to is_fifo(status(p, ec)). Returns false and sets ec to an appropriate error code if an error occurs. Otherwise, ec is cleared with a call to ec.clear().

---

🎀 Parameters 🎀

• s — file status to check
• p — path to query
• ec — error code to modify in case of errors

---

⭐ Return value ⭐

Returns true if the given path or file status corresponds to a FIFO file. Iconic. ✅

---

🔥 Exceptions 🔥

• 1,3) — noexcept specification: noexcept
• 2) — Throws filesystem_error if an error occurs. The exception object is constructed with p as an argument.
