The documentation for Glib function /g_source_set_callback ()/ tells this:
"The exact type of /|func|/ depends on the type of source; ie. you
should not count on /|func|/ being called with /|data|/ as its first
parameter."
What does it exactly mean? The callback function has the type:
gboolean
<https://developer.gnome.org/glib/stable/glib-Basic-Types.html#gboolean> (*GSourceFunc) (/|gpointer
<https://developer.gnome.org/glib/stable/glib-Basic-Types.html#gpointer>
user_data|/);
So what should I expect as a parameter when glib calls my callback
function with a /gpointer/ data. How can I find *my* data?
