| 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); std::cout << "Error code from io_errc::stream has category " << ec.category().name() << '\n'; }
Output:
Error code from io_errc::stream has category iostream
