From 3e6bdd90c604e061c71715865eb403ffdd0dd7f0 Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Wed, 21 Oct 2020 10:03:23 -0400 Subject: [PATCH] XRes: Use _XRead instead of _XRead32 for reading pid _XRead32 requires the output variable to be a long, but `ReadClientValues` feeds it client->value which is a 32-bit allocation. This commit changes the code to use _XRead instead, which properly handles 32-bit output variables. https://gitlab.freedesktop.org/xorg/lib/libxres/-/issues/3 --- src/XRes.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/XRes.c b/src/XRes.c index 2bee277..90e72c9 100644 --- a/src/XRes.c +++ b/src/XRes.c @@ -256,7 +256,7 @@ static Bool ReadClientValues( _XRead32 (dpy, &value, 4); client->length = value; client->value = malloc(client->length); - _XRead32 (dpy, client->value, client->length); + _XRead (dpy, client->value, client->length); } return True; } -- 2.28.0
