From 7118692e506f9698a77c7cceea3b1dd47bb4b99a Mon Sep 17 00:00:00 2001 From: Thomas Voss Date: Thu, 13 Oct 2022 00:03:37 +0200 Subject: Move functions to their own files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Also we move the source code to a src/ directory. We also move from using `struct luxdisp` to `lux_t` to signify that we don’t want the user to be messing with the struct members. --- src/luxget.c | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 src/luxget.c (limited to 'src/luxget.c') diff --git a/src/luxget.c b/src/luxget.c new file mode 100644 index 0000000..39c3b6f --- /dev/null +++ b/src/luxget.c @@ -0,0 +1,39 @@ +/* + * BSD Zero Clause License + * + * Copyright (c) 2022 Thomas Voss + * + * Permission to use, copy, modify, and/or distribute this software for any + * purpose with or without fee is hereby granted. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH + * REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY + * AND FITNESS.
