From 64b51eb68bd272b6b1f2cefa2b33e9dd74024d0c Mon Sep 17 00:00:00 2001 From: Philipp Maier Date: Mon, 14 Jan 2019 11:59:11 +0100 Subject: socket: add define for socket name length The function osmo_sock_get_name_buf() can be used to write a string representation to a user provided memory. Unfortunately the proper length for the user provided memory is not obvious. To make using osmo_sock_get_name_buf() more practical, add a define constant that defines the length of the required memory. Also use this define in socket.c.
