# High performance C++11 signals

See [Performance of a C++11 Signal System](http://www.testbit.eu/2013/cpp11-signal-system-performance/) for

the original source code, as well as performance measurements compared to other signalling systems.

## Declare a signal

This example declares a signal 'sig' that takes three arguments and returns a char.

```c++

Simple::Signal sig;

```

## Connect to a signal

This example connects 'sig' to a static function.

It is also possible to connect to member functions or lambda functions.

```c++

static char float_callback (float f, int, std::string) {

  // ...

  return 0;

}

void Init() {

  sig.connect(float_callback);

}

```

## Fire a signal

```c++

void func() {

  // ...

  sig.emit(1.0f, 7, "xxxx");

}

```
