xtd::scope_exit Struct Reference

Definition

Nowadays, every C++ developer is familiar with the Resource Acquisition Is Initialization (RAII) technique. It binds resource acquisition and release to initialization and destruction of a variable that holds the resource. There are times when writing a special class for such a variable is not worth the effort. This is when xtd xtd::scope_exit comes into play.

Namespace

xtd

Library

xtd.core

Remarks

See also scope_exit_ keyword helper.

Warning

Prefer use RAII then xtd::scope_exit.

#include <xtd/xtd>
 
using namespace xtd;
 
auto main() -> int {
  static auto __scope_exit__ = scope_exit {} + [&] {
    console::write_line("scope_exit");
  };
  console::write_line("begin");
  //...
  console::write_line();
  console::write_line("do something...");
  console::write_line();
  //...
  console::write_line("end");
}
 
// This code produces the following output:
//
// begin
//
// do something...
//
// end
// scope_exit
