From 2535ba7006f22a6470f4c88ea7d30c343a1d8799 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Thu, 28 Sep 2017 17:17:45 +0200 Subject: src: get rid of printf This patch introduces nft_print()/nft_gmp_print() functions which have to be used instead of printf to output information that were previously send to stdout. These functions print to a FILE pointer defined in struct output_ctx. It is set by calling: | old_fp = nft_ctx_set_output(ctx, new_fp); Having an application-defined FILE pointer is actually quite flexible: Using fmemopen() or even fopencookie(), an application gains full control over what is printed and where it should go to.
