libsigc++ implements a typesafe 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. This is the libsigc++-3.0 API, which installs in parallel with libsigc++-2.0. The API is not significantly different, but the implementation is far simpler, using variadic templates instead of generating C++ code from .m4 filessystem.
