From: Jason McDonald Date: Fri, 26 Aug 2011 07:36:55 +0000 (+1000) Subject: Send error messages to stderr rather than stdout X-Git-Tag: qt-v5.0.0-alpha1~3744 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=15400d94664f93dc22f71802eb72c34c52e371ac;p=profile%2Fivi%2Fqtbase.git Send error messages to stderr rather than stdout The commit changes printf's that output error and warning messages to send their text to the stderr stream. Non-error output, such as that produced by passing the -help option to a test, still goes to stdout.
