std::error_condition make_error_condition( std::io_errc e ) noexcept; | (since C++11) |
Constructs an std::error_condition
object from a value of type std::io_errc
as if by return std::error_condition(static_cast<int>(e), std::iostream_category())
.
e | - | error code number |
A value of type std::error_condition
that holds the error code number from e
associated with the error category "iostream"
.
#include <iostream> #include <system_error> #include <string> int main() { std::error_condition ec = std::make_error_condition(std::io_errc::stream); std::cout << "error condition for io_errc::stream has value " << ec.value() << "\nand message \"" << ec.message() << "\"\n"; }
Output:
error condition for io_errc::stream has value 1 and message "unspecified iostream_category error"
(C++11) | holds a portable error code (class) |
(C++11) | the IO stream error codes (enum) |
