std::io_errc - cppreference.com (original) (raw)
| Defined in header | | | | -------------------------------------------------------------- | | ------------- | | enum class io_errc { stream = 1, }; | | (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.

[edit] Example
#include #include 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
