From 63e7e57237a79d0447b0450a7fd3148c43052299 Mon Sep 17 00:00:00 2001 From: David Robillard Date: Fri, 13 Aug 2021 19:31:26 -0400 Subject: Provide a full output stream implementation for SerdBuffer Essentially replaces serd_buffer_sink_finish() with serd_buffer_close(), which makes writing to a buffer consistent with writing to a file or anything else. --- src/buffer.c | 52 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 src/buffer.c (limited to 'src/buffer.c') diff --git a/src/buffer.c b/src/buffer.c new file mode 100644 index 00000000..85ec09de --- /dev/null +++ b/src/buffer.c @@ -0,0 +1,52 @@ +/* + Copyright 2011-2021 David Robillard + + Permission to use, copy, modify, and/or distribute this software for any + purpose with or without fee is hereby granted, provided that the above + copyright notice and this permission notice appear in all copies. + + THIS SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + MERCHANTABILITY AND FITNESS.
