std::io_errc
From cppreference.com
| Defined in header <ios>
|
||
| enum class io_errc; |
(since C++11) | |
The scoped enumeration std::io_errc defines the error codes reported by I/O streams in std::ios_base::failure exception objects. Only one error code (std::io_errc::stream) is required, although the implementation may define additional error codes. Because the appropriate specialization of std::is_error_code_enum is provided, values of type std::io_errc are implicitly convertible to std::error_code.
Member constants
| Enumeration constant | Value |
stream
|
1 |
Non-member functions
| constructs an iostream error code (function) | |
| constructs an iostream error_condition (function) |
Helper classes
| extends the type trait std::is_error_code_enum to identify iostream error codes (class template) |
Example
Run this code
#include <iostream> #include <fstream> int main() { std::ifstream f("doesn't exist"); try { f.exceptions(f.failbit); } catch (const std::ios_base::failure& e) { std::cout << "Caught an ios_base::failure.\n"; if(e.code() == std::io_errc::stream) std::cout << "The error code is std::io_errc::stream\n"; } }
Output:
Caught an ios_base::failure. The error code is std::io_errc::stream
