From 86271b3717f1aa499457b75caf1d44e0e64bda6b Mon Sep 17 00:00:00 2001 From: Colomban Wendling Date: Tue, 7 Nov 2023 15:23:47 +0100 Subject: Fix various instance checks The g_return*_if_fail() calls should use PREFIX_IS_TYPE_NAME [1], which returns whether the given instance is of the right type, not PREFIX_TYPE_NAME [2], which checks whether the given instance if of the right type, warns if not, and returns the passed-in instance unchanged. Using the wrong one means the returned value is the passed-in pointer, and thus passes the g_return*_if_fail() whenever the pointer is non-NULL, no matter whether it's of the right type or not. A warning would still be emitted by g_type_check_instance_cast(), but the execution wouldn't get short-circuited. [1] calls g_type_check_instance_is_a() [2] calls g_type_check_instance_cast() --- mate-volume-control/gvc-level-bar.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'mate-volume-control/gvc-level-bar.c') diff --git a/mate-volume-control/gvc-level-bar.c b/mate-volume-control/gvc-level-bar.c index ccf141b..13e7aeb 100644 --- a/mate-volume-control/gvc-level-bar.c +++ b/mate-volume-control/gvc-level-bar.c @@ -295,7 +295,7 @@ void gvc_level_bar_set_peak_adjustment (GvcLevelBar *bar, GtkAdjustment *adjustment) { - g_return_if_fail (GVC_LEVEL_BAR (bar)); + g_return_if_fail (GVC_IS_LEVEL_BAR (bar)); g_return_if_fail (GTK_IS_ADJUSTMENT (adjustment)); if (bar->priv->peak_adjustment != NULL) { @@ -321,7 +321,7 @@ void gvc_level_bar_set_rms_adjustment (GvcLevelBar *bar, GtkAdjustment *adjustment) { - g_return_if_fail (GVC_LEVEL_BAR (bar)); + g_return_if_fail (GVC_IS_LEVEL_BAR (bar)); g_return_if_fail (GTK_IS_ADJUSTMENT (adjustment)); if (bar->priv->rms_adjustment != NULL) { -- cgit v1.2.1
