std::error_...::equivalent(3)

🌸 NAME 🌸

okay bestie, welcome to std::error_...::equivalent(3) from the C++ Standard Libary manual ✨ (yes, that's the manual name, keeping it exactly as it is). This page is all about std::error_category::equivalent — and the name line is literally std::error_category::equivalent again, which is giving main character energy 💅.

✨ Synopsis ✨

so std::error_category::equivalent has two virtual overloads, both since C++11 🫶. They check whether an error code is equivalent to an error condition for the error category represented by *this.

1. (since C++11) virtual bool equivalent( int code, const std::error_condition& condition ) const noexcept;
2. (since C++11) virtual bool equivalent( const std::error_code& code, int condition ) const noexcept;

what they actually do, lowkey:

• Overload 1 is equivalent to default_error_condition(code) == condition.
• Overload 2 is equivalent to *this == code.category() && code.value() == condition.

🎀 Parameters 🎀

• code — specifies the error code to compare.
• condition — specifies the error condition to compare.

💖 Return value 💖

true if the error code is equivalent to the given error condition for the error category represented by *this, false otherwise. periodt 💅✨

okay bestie, that's the whole page 🫶 — source/version vibes: http://cppreference.com, and the date on this one is 2024.06.10. mwah 💋🎀
