From 9c3669c6b7ff19013b3684bb74d98ec3d121e329 Mon Sep 17 00:00:00 2001 From: Mike Gabriel Date: Mon, 27 Feb 2017 13:52:29 +0000 Subject: Xserver/dix/atom.c (et al.): Constify atom name strings. Inspired by X.org commits: commit 08093c25a91c07ab8af7cece9bba738b827cfd1b Author: Alan Coopersmith Date: Mon Oct 24 23:16:30 2011 -0700 Convert some malloc + strncpy pairs into strndup calls Signed-off-by: Alan Coopersmith Reviewed-by: Jeremy Huddleston commit 816b79dd061e9839cec94a4986a7820b70ca8a7f Author: Mikhail Gusarov Date: Thu May 13 03:45:21 2010 +0700 Remove useless casts Signed-off-by: Mikhail Gusarov Reviewed-by: Keith Packard This PR ships a tiny change in MakeAtom, that we adopted. We did not adopt the full commit. commit 5623c27700b7b23a8dbbd8c8f45e5d4fa0c667e3 Author: Alan Coopersmith Date: Mon Feb 2 19:25:14 2009 -0800 Constify atom name strings Changes MakeAtom to take a const char * and NameForAtom to return them, since many callers pass pointers to constant strings stored in read-only ELF sections. Updates in-tree callers as necessary to clear const mismatch warnings introduced by this change.
