Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

== NAME ==
|
|
'''archive_write_data''',
|
|
'''archive_write_data_block'''
|
|
- functions for creating archives
|
|
== LIBRARY ==
|
|
Streaming Archive Library (libarchive, -larchive)
|
|
== SYNOPSIS ==
|
|
'''<nowiki>#include <archive.h></nowiki>'''
|
|
<br>
|
|
''la_ssize_t''
|
|
<br>
|
|
'''archive_write_data'''(''struct archive *'', ''const void *'', ''size_t'');
|
|
<br>
|
|
''la_ssize_t''
|
|
<br>
|
|
'''archive_write_data_block'''(''struct archive *'', ''const void *'', ''size_t size'', ''int64_t offset'');
|
|
== DESCRIPTION ==
|
|
<dl>
|
|
<dt>'''archive_write_data'''()</dt><dd>
|
|
Write data corresponding to the header just written.
|
|
</dd><dt>'''archive_write_data_block'''()</dt><dd>
|
|
Write data corresponding to the header just written.
|
|
This is like
|
|
'''archive_write_data'''()
|
|
except that it performs a seek on the file being
|
|
written to the specified offset before writing the data.
|
|
This is useful when restoring sparse files from archive
|
|
formats that support sparse files.
|
|
Returns number of bytes written or -1 on error.
|
|
(Note: This is currently not supported for
|
|
'''archive_write'''
|
|
handles, only for
|
|
'''archive_write_disk'''
|
|
handles.
|
|
</dd></dl>
|
|
== RETURN VALUES ==
|
|
This function returns the number of bytes actually written, or
|
|
a negative error code on error.
|
|
== ERRORS ==
|
|
Detailed error codes and textual descriptions are available from the
|
|
'''archive_errno'''()
|
|
and
|
|
'''archive_error_string'''()
|
|
functions.
|
|
== BUGS ==
|
|
In libarchive 3.x, this function sometimes returns
|
|
zero on success instead of returning the number of bytes written.
|
|
Specifically, this occurs when writing to an
|
|
''archive_write_disk''
|
|
handle.
|
|
Clients should treat any value less than zero as an error
|
|
and consider any non-negative value as success.
