Glib::IOSource::IOSource ( GSource *  cast_item, GSourceFunc  callback_func  )

protected

Wrap an existing GSource object and install the given callback function.

This constructor is for use by derived types that need to wrap a GSource object. The callback function is called from GLib (a C library). It shall have C linkage. (Many compilers accept a function with C++ linkage. If you use only such compilers, the callback function can be a static member function.)
