From d9c27253ce333e2086b2d758b42dc3ecb8b34c3d Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sun, 20 Jun 2010 17:14:14 +0200 Subject: Make *printf() return "int" instead of "void" Change the return type of the *printf() functions to the standard "int"; no changes are needed but returning the already available length count. This will save a few additional strlen() calls later...
