std::system_error(3)

💖 NAME 💖

okay so bestie, welcome to std::system_error — it's a whole exception type that comes with an error_code value attached, like a lil gift bag of "what went wrong" 🎀

---

✨ SYNOPSIS ✨

#include <system_error>

It inherits std::runtime_error. no cap.

And it gets inherited by these three icons right here:

• std::experimental::filesystem::v1::filesystem_error
• std::filesystem::filesystem_error
• std::ios_base::failure

🫶 Public Member Functions 🫶

here's the whole roster, no skips, no cuts:

system_error (const system_error &)=default
system_error (error_code __ec, const char *__what)
system_error (error_code __ec, const string &__what)
system_error (error_code __ec=error_code())
system_error (int __v, const error_category &__ecat)
system_error (int __v, const error_category &__ecat, const char *__what)
system_error (int __v, const error_category &__ecat, const string &__what)
const error_code & code () const noexcept
system_error & operator= (const system_error &)=default
virtual const char * what () const noexcept

🌸 Detailed Description 🌸

An exception type that includes an error_code value. that's the whole vibe. 💅

Typically used to report errors from the operating system and other low-level APIs. like when the OS is being messy and you need receipts fr fr.

Since

C++11 — yeah she's been iconic for a while, not a new girl. 👑

💜 Member Function Documentation 💜

virtual const char * std::runtime_error::what () const [virtual], [noexcept], [inherited]

Returns a C-style character string describing the general cause of the current error — and it's literally the same string that was passed to the ctor. no rewriting, no glow-up, same string. 😭

Reimplemented from std::exception.

Reimplemented in std::experimental::filesystem::v1::filesystem_error, std::filesystem::filesystem_error, and std::ios_base::failure.

References what().

Referenced by what().

not me pointing out that what() references what() and is referenced by what() 💀 that's the recursion-flavored main character energy, we don't ask questions, we just report it exactly as it is.

okay that's the whole page bestie, you understood it, you slayed it, go catch some errors with your error_code in hand 🫶🌸

this has been your girl, std::system_error(3), from the Library Functions Manual, brought to you by libstdc++ — mwah, stan the standard library 💖⭐
