std::ios_base::failure(3cxx)

💅 std::ios_base::failure — like, the 3cxx manual page, bestie

okay so welcome to std::ios_base::failure(3cxx), the page about the exception that shows up when your io is going through it 😭✨ It lives in the <ios> header and, ngl, it's the main character of "something went wrong with io."

---

🌸 NAME 🌸

std::ios_base::failure — these are thrown to indicate problems with io 💖

---

✨ SYNOPSIS ✨

#include <ios>

Inherits std::exception. That's its whole personality trait, honestly — it's a std::exception girlie 🎀

🫶 Public Member Functions

• failure (const char *__s, const error_code &=error_code{}) — constructor #1, takes a C-style string plus an error_code that defaults to error_code{} 🌸
• failure (const string &__s, const error_code &) noexcept — constructor #2, string + error_code, and it's noexcept so she will not be throwing at you twice 💅
• failure (const string &__str) throw () — constructor #3, just the string, marked throw ()
• error_code code () const noexcept — hands you back the error_code, noexcept
• virtual const char * what () const throw () — the classic what(), virtual, const, throw ()

Also like — the source says, verbatim: 27.4.2.1.1 Class ios_base::failure. Like, that's literally the standard section number, iconic ✨ iykyk.

🦋 Member Function Documentation 🦋

Fr fr, this page ships as part of libstdc++ in the 3cxx man section — so when you're RTFM-ing at 2am, that's the source and the section, bestie 🫶💖 Go read your io errors and slay, mwah 🎀✨
