From 6aca702d252e108801b99113149fec1e89434167 Mon Sep 17 00:00:00 2001
From: "A. Wilcox" <AWilcox@Wilcox-Tech.com>
Date: Wed, 14 Mar 2018 23:25:31 -0500
Subject: [PATCH] Process: Don't use stdio identifiers for methods
`stdout` and `stderr` are already used by POSIX <stdio.h>. This has
already caused problems in the past as the (now removed) comment in
Process.cpp noted with compilation on Mac OS X.
This also causes a problem compiling on the musl libc, which
specifically uses the preprocessor to avoid redefinition and changing of
stdin, stdout, and stderr.
This patch changes the names to be stdErr and stdOut, which are
camel-cased like Qt methods typically are, and do not conflict with
identifiers defined in <stdio.h>.
