From bd28075ee0bf121ef4fe50e34146efe14acee07b Mon Sep 17 00:00:00 2001 From: Arturo Borrero Date: Tue, 29 Oct 2013 23:44:25 +0100 Subject: src: add fprintf API functions Now it's possible to print directly from libnftables to a file or other stream. The caller must explicitly print the trailing '\n' in this call. The error reporting of fprintf (< 0) is respected. However, we have already print some information in case that the default (plain text) output is used, that output is mostly intended for debugging so it should not be a problem.
