La portée
std::io_errc énumération définit les codes d'erreur générés par les flux d'E / S dans les objets d'exception std::ios_base::failure. Un seul code d'erreur (std::io_errc::stream) est nécessaire, même si la mise en œuvre peut définir des codes d'erreur supplémentaires. Parce que la spécialisation approprié de std :: is_error_code_enum est fourni, les valeurs de type std::io_errc sont implicitement convertible en std::error_code .Original:
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.The text has been machine-translated via Google Translate.

[modifier] Exemple
#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"; } }
Résultat :
Caught an ios_base::failure. The error code is std::io_errc::stream
