From af9413b539628b0758b4af66ffbb879fba49cc6d Mon Sep 17 00:00:00 2001 From: kientzle Date: Mon, 9 Feb 2004 23:22:54 +0000 Subject: Initial import of libarchive. What it is: A library for reading and writing various streaming archive formats, especially tar and cpio. Being a library, it should be easy to incorporate into pkg_* tools, sysinstall, and any other place that needs to read or write such archives. Features: * Full automatic detection of both compression and archive format. * Extensible internal architecture to make it easy to add new formats. * Support for "pax interchange format," a new POSIX-standard tar format that eliminates essentially all of the restrictions of historic formats. * BSD license Thanks to: jkh for pushing me to start this work, gordon for encouraging me to commit it, bde for answering endless style questions, and many others for feedback and encouragement. Status: Pretty good overall, though there are still a few rough edges and the library could always use more testing. Feedback eagerly solicited. --- lib/libarchive/archive_read_data_into_buffer.c | 52 ++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 lib/libarchive/archive_read_data_into_buffer.c (limited to 'lib/libarchive/archive_read_data_into_buffer.c') diff --git a/lib/libarchive/archive_read_data_into_buffer.c b/lib/libarchive/archive_read_data_into_buffer.c new file mode 100644 index 0000000..988a2bf --- /dev/null +++ b/lib/libarchive/archive_read_data_into_buffer.c @@ -0,0 +1,52 @@ +/*- + * Copyright (c) 2003-2004 Tim Kientzle + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
