std::error_code make_error_code( std::io_errc e ); | (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"
.
Exceptions
noexcept
specification: noexcept
Example
#include <iostream> #include <system_error> int main() { std::error_code ec = std::make_error_code(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
