From 37d0f55392d68d0a05dcf5d793d729e49108f1b7 Mon Sep 17 00:00:00 2001 From: Ran Benita Date: Sun, 4 Aug 2013 13:31:29 +0300 Subject: xkb: Work around alignment problems in GetNames and GetMap replies The basic situation is this: a list of CARD8/CARD16s followed by a list of CARD16/CARD32s. In the current code, the second list is aligned to 1/2 bytes according the size of the first list. However, in some cases the second list needs to be aligned to 4 bytes per the xkbproto spec: http://www.x.org/releases/current/doc/kbproto/xkbproto.html#appD::Requests XkbGetMap reply (xkb-opcode 8): [...] a LISTofCARD8 actsRtrn.count p unused,p=pad(a) 8A LISTofKB_ACTION actsRtrn.acts 4B LISTofKB_SETBEHAVIOR behaviorsRtrn v LISTofSETofKEYMASK vmodsRtrn p unused, p=pad(v) 2E LISTofKB_SETEXPLICIT explicitRtrn p unused,p=pad(2E) 2M LISTofKB_KEYMODMAP modmapRtrn p unused, p=pad(2M) [...] XkbGetNames reply (xkb-opcode 17): [...] l LISTofCARD8 nLevelsPerType, sum of all elements=L p unused, p=pad(l) [...] The server and Xlib handle this with calls to XkbPaddedSize(), which is a good way to see where the extra padding is needed.
