🦋 STD::__UNSPECIFIED___EXCEPTION_PTR(3) — Library Functions Manual 🦋

okay so bestie, welcome to the manual page for the mysterious little handle known as std::__unspecified__::exception_ptr 💅 — it lives in the Library Functions Manual, and it’s giving “opaque pointer to an arbitrary exception” energy. ✨

🌸 NAME 🌸

std::__unspecified__::exception_ptr — an opaque pointer to an arbitrary exception.

That’s the whole vibe: it’s an opaque pointer to an arbitrary exception, so you’re not peeking inside the exception itself through this type. 🫶

✨ SYNOPSIS ✨

🎀 Public Member Functions 🎀

Here’s the full roster, with every noexcept left exactly where it belongs:

exception_ptr (const exception_ptr &) noexcept
exception_ptr (exception_ptr &&__o) noexcept
exception_ptr (nullptr_t) noexcept
const class std::type_info * __cxa_exception_type () const noexcept
operator bool () const noexcept
exception_ptr & operator= (const exception_ptr &) noexcept
exception_ptr & operator= (exception_ptr &&__o) noexcept
void swap (exception_ptr &) noexcept

Copy-construct it, move-construct it, construct from nullptr_t, ask it for the exception type via __cxa_exception_type, bool-check it, copy-assign it, move-assign it, or swap it — all with noexcept and all iconic. 💅

🦋 Friends 🦋

These are the friend functions, and yes, the noexcept=default and line breaks are part of the whole look:

bool operator== (const exception_ptr &, const exception_ptr &)
    noexcept=default
exception_ptr std::current_exception () noexcept
template<typename _Ex > exception_ptr std::make_exception_ptr (_Ex)
    noexcept
void std::rethrow_exception (exception_ptr)

Note that these are not member functions.

void swap (exception_ptr &__lhs, exception_ptr &__rhs)
bestie PSA: that swap is related, not a member function. Don’t get it twisted. 💀

💖 Detailed Description 💖

An opaque pointer to an arbitrary exception. ✨

The actual name of this type is unspecified, so the alias std::exception_ptr should be used to refer to it. Periodt — that’s the name you’re meant to use. 💅

💫 Since 💫

  • C++11 (but usable in C++98 as a GCC extension) — yes bestie, it has range. 🌈
