Until now, the RPC framework did not support const RPC functions. Rather than being a limitation inherent to the concept, const RPC functions plainly did not exist. So supporting them was not deemed too important. However, there are uses of RPC interfaces that would benefit from a way to declare an RPC function as const. Candidates are functions like 'Framebuffer::Session::mode()' and 'Input::Session::is_pending()'. This patch clears the way towards declaring such functions as const. Even though the patch is simple enough, the thorough support for const-qualified RPC functions would double the number of overloads for the 'call_member' function template (in 'base/include/util/meta.h'). For this reason, the patch does support const getter functions with no arguments only. This appears to be the most common use of such functions. |
