std::make_error_code(std::io_errc)
From cppreference.com
Defined in header <ios>
|
||
std::error_code make_error_code( std::io_errc e ) noexcept; |
(since C++11) | |
Constructs an std::error_code object from a value of type std::io_errc as if by return std::error_code(static_cast<int>(e), std::iostream_category()). This function is called by the constructor of std::error_code when given an std::io_errc argument.
Parameters
e | - | error code number |
Return value
A value of type std::error_code that holds the error code number from e
associated with the error category "iostream".
Example
Run this code
#include <iostream> #include <system_error> int main() { std::error_code ec = std::make_error_code(std::io_errc::stream); // This works because of the overloaded method // and the is_error_code_enum specialization. ec = std::io_errc::stream; std::cout << "Error code from io_errc::stream has category " << ec.category().name() << '\n'; }
Output:
Error code from io_errc::stream has category iostream
