Non-member functions
(C++11) |
constructs an std::errc error code (function) |
constructs an std::errc error condition (function) |
Helper classes
extends the type trait std::is_error_condition_enum to identify the the std::errc values as error conditions (function template) |
Example
Run this code
#include <iostream> #include <system_error> #include <thread> int main() { try { std::thread().detach(); // detaching a not-a-thread } catch (const std::system_error& e) { std::cout << "Caught a system_error\n"; if(e.code() == std::errc::invalid_argument) std::cout << "The error condition is std::errc::invalid_argument\n"; std::cout << "the error description is " << e.what() << '\n'; } }
Output:
Caught a system_error The error condition is std::errc::invalid_argument the error description is Invalid argument
