From 1b3a1c277a033083fee669e92c8cad862716ebd1 Mon Sep 17 00:00:00 2001 From: Uli Schlachter Date: Sun, 7 Mar 2021 08:42:54 +0100 Subject: Remove three more round trips There are a number of XKB requests needed to request all the information from the X11 server. So far, the code was sending one request and waiting for the reply. This commit starts batching the request so that we get multiple replies with one round trip. This removes three round trips. Only the simple requests are converted. get_map() and get_names() use some bitmasks that are needed for both the request and the reply. These will be dealt with separately.
