std::error_condition(3cxx)

🌸 NAME 🌸

std::error_condition — that's the class, bestie. The manual name is 3cxx (libstdc++ C++ manual-page energy), and this whole page is literally the std::error_condition(3cxx) moment. 💅✨

✨ SYNOPSIS ✨

#include <system_error>

🎀 Public Member Functions 🎀

• error_condition () noexcept — Initialize with a zero (no error) value and the generic category.
• template<typename _ErrorConditionEnum , typename = _Check<_ErrorConditionEnum>> error_condition (_ErrorConditionEnum __e) noexcept — Initialize with a user-defined type, by calling make_error_condition.
• error_condition (const error_condition &)=default — defaulted, no extra description given.
• error_condition (int __v, const error_category &__cat) noexcept — Initialize with the specified value and category.
• void assign (int __v, const error_category &__cat) noexcept — Set the value and category.
• const error_category & category () const noexcept — The error category that this error belongs to.
• void clear () noexcept — Reset the value and category to the default-constructed state.
• string message () const — The category's description of the value.
• operator bool () const noexcept — Test whether value() is non-zero.
• error_condition & operator= (const error_condition &)=default — defaulted, no extra description given.
• int value () const noexcept — The error value.

💖 Detailed Description 💖

Class error_condition

This class represents error conditions that may be visible at an API boundary. Different error_code values that can occur within a library or module might map to the same error_condition.

An error_condition represents something that the program can test for, and subsequently take appropriate action.

Since: C++11 🌈

💖 okay bestie, that's the whole page: source/version libstdc++, manual name std::error_condition(3cxx), and the original footer doesn't print a date, so I'm not gonna invent one — no cap. Bye-bye! 🫶✨
