Declare a function with return type and parameters matching the prototype below:
void ChangeCallback( IConVar* var, const char* pOldValue, float pOldValue );
Then implement it (read the old value into a temporary string, say, a
CUtlString, strip the spaces, then set the new value using
var->SetValue(const char*))
In your init code put the following
empty_cvar.InstallChangeCallback(&ChangeCallback);
OR
Modify the constructor to look like:
static ConVar empty_cvar("plugin_empty", "0", 0, "Example plugin
cvar", &ChangeCallback);
