std::bad_typeid(3)

💖 std::bad_typeid 💖

okay bestie, welcome to the std::bad_typeid page from the Library Functions Manual — yes that's the man page section 3 situation, we're in library-functions territory, pull up a chair 🫶

✨ NAME ✨

std::bad_typeid — the exception that gets thrown when a NULL pointer in a typeid expression is used. that's it, that's the whole job, and it does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

#include <typeinfo>

Inherits std::exception. so like, it's part of the family, it's got the whole std::exception bloodline going on 👑

🎀 Public Member Functions 🎀

• virtual constexpr const char * what () const noexcept

---

🦋 Detailed Description 🦋

Thrown when a NULL pointer in a typeid expression is used.

literally that's the entire vibe. you dereference-ish a NULL pointer inside typeid, and the standard library said "not today" and handed you one of these instead 😭✨

💜 Member Function Documentation 💜

virtual constexpr const char * std::bad_typeid::what () const [inline], [constexpr], [virtual], [noexcept]

Returns a C-style character string describing the general cause of the current error.

Reimplemented from std::exception. so it's doing the classic what() thing but its own way, main character energy fr fr 🔥

no cap: every single qualifier on that signature matters — inline, constexpr, virtual, noexcept, all of them. copy it exactly if you're writing it down, bestie 🎀
