Multipurpose key logger for Windows and macOS writhen in C++
Requires C++ 20, tested on apple clang 14 and VC++ 14
Overhead is about 1~2 mircoseconds(on first callback invocation)

On macOS, please add 'ApplicationServices.framework' to the project

1. create an logger object

auto example_logger = event::keyboard::logger<callback, container, traits, event_mask...>();

2. set callback function

example_logger.set_callback(callback_function);

3. start

example_logger.start();

4. cleanup

example_logger.stop();

• Null container

  event::null_container = event::null_template_type

• Stored Containers

  event::vector -> std::vector  
  event::queue  -> std::queue  
  event::deque  -> std::deque  

• Table Containers

  event::array  -> std::array
  event::bitset -> std::bitset

• Null callback

  event::null_container = event::null_type

• Function types

  type                      -> std::function<void(type)>  
  return_type(param...)     -> std::function<return_type(parameter...)>  
  return_type(*)(param...)        
  return_type(class::*)(param...) 
  std::function<return_type(param)...>  
  lambda  

• Key press

  event::action::key_down

• Key release

  event::action::key_up

• System keys

  event::action::key_system
