The C++ Callback library described in my article in the February '95
issue of the C++ Report is now freely available. The library is an
implementation of callbacks using template functors. It is a portable, general
purpose library for building loosely coupled systems in a type-safe manner.

The library is free. Full source and some test and sample code are provided.
Included documentation is slim, but the article describes the library and its
rationale in detail.

It is available via anonymous ftp at:

ftp.crl.com

in directory:

/users/ro/jmorey/callback

It is also available on Compuserve:

BCPPDOS forum, Library 6, file: CALLBK.ZIP

It has been successfully tested with

IBM CSet++
Borland 4.02 & 4.5
Watcom 10.0

Note that some UNIX compilers are not yet able to compile the library.
These may be 'work-aroundable', don't know yet.

VC++ 2.0 cannot currently compile the library.
No workaround until some fundamental compiler bugs fixed.

I encourage all to try it, and welcome feedback.

Enjoy!
