* [Report bugs](https://github.com/boostorg/function/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt).
* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[function]` tag at the beginning of the subject line.

# Generic Appveyor build script for boostorg repositories
# See: https://github.com/jeking3/boost-ci/
#
# Instructions for customizing this script for your library:
#
# 1. Customize the compilers and language levels you want.
# 2. If you have move than include/, src/, test/, example/, examples/,
# benchmark/ or tools/ directories, set the environment variable DEPINST.
# For example if your build uses code in "bench/" and "fog/" directories:
# - DEPINST: --include bench --include fog
# 3. Enable pull request builds in your boostorg/<library> account.
#
# That's it - the script will do everything else for you.

<title>Function object wrapper size</title>
<para> Function object wrappers will be the size of a struct containing a member function pointer and two data pointers. The actual size can vary significantly depending on the underlying platform; on 32-bit Mac OS X with GCC, this amounts to 16 bytes, while it is 32 bytes Windows with Visual C++. Additionally, the function object target may be allocated on the heap, if it cannot be placed into the small-object buffer in the <code>boost::function</code> object.</para>
<para> Function object wrappers will be the size of two function pointers plus one function pointer or data pointer (whichever is larger). On common 32-bit platforms, this amounts to 12 bytes per wrapper. Additionally, the function object target will be allocated on the heap.</para>

<section>
<title>Copying efficiency</title>
<para> Copying function object wrappers may require allocating memory for a copy of the function object target. The default allocator may be replaced with a faster custom allocator or one may choose to allow the function object wrappers to only store function object targets by reference (using <computeroutput>ref</computeroutput>) if the cost of this cloning becomes prohibitive. Small function objects can be stored within the <code>boost::function</code> object itself, improving copying efficiency.</para>
