# C++ Callback Library: PlusCallback

*Additional documentation at:*

http://codeplea.com/pluscallback

## Intro

PlusCallback is a C++ library, contained in a single header file, that

implements easy to use function and method callbacks. It is completely

contained in one header file, so it's trivial to add to your projects. It also

uses the simplest syntax of any callback method I've ever seen (for C++), and

it's quite flexible.

## Code Sample

    //Setup callback for TestObject.Foo().

    cb::Callback1 callback(&TestObject, &TestClass::Foo);

    //Call TestObject.Foo(5).

    callback(5);

    //Change callback to a free function.

    callback = SomeRandomFunction;

    //Call SomeRandomFunction(8).

    callback(8);

## Features

- Contained in one header file, trivial to install

- Portable ANSI C++ code

- Completely free for any use (zlib license)

- Very simple API

- Type-safe, no macros or casts

- Container storage safe (e.g. std::map, list, vector, etc)

## Installation Instructions

This entire library is contained in one header file.

Simply include *callback.hpp* in your project.

## Examples

Some examples are included in the examples directory:

- example.cpp - PlusCallback example walking through most features.

- compare.cpp - Example comparing different callback methods.

- smoke.cpp   - Several random tests for PlusCallback.

## Building Instructions

This library comes pre-built. If you would like to rebuild this

library, you need to run build.tcl with the TCL interpreter. You

can obtain TCL from http://www.tcl.tk/

When rebuilding, you can change the maximum number of parameters

supported by callbacks.
