Subject: [PATCH BlueZ v2 1/3] doc/hci-protocol: Fix missing & on mtu argument in BT_RCVMTU example
Date: Sun, 30 Aug 2026 22:39:29 -0700 [thread overview]
Message-ID: <20260830-vendor_hci-v2-1-9903760957ab@oss.qualcomm.com> (raw)
In-Reply-To: <20260830-vendor_hci-v2-0-9903760957ab@oss.qualcomm.com>
getsockopt() requires a pointer argument, but mtu was passed by value.
Fix by using &mtu instead of mtu.
