libsigc++ 2.10.3 Type-safe callback system for standard C++

This is a GNU package.

Libsigc++ implements a type-safe callback system for standard C++. It allows you to define signals and to connect those signals to any callback function, either global or a member function, regardless of whether it is static or virtual.

It also contains adaptor classes for connection of dissimilar callbacks and has an ease of use unmatched by other C++ callback libraries.
