NAME¶
libzip — library
for manipulating zip archives
LIBRARY¶
libzip (-lzip)
SYNOPSIS¶
#include
<zip.h>
DESCRIPTION¶
libzip is a library for reading, creating,
and modifying zip archives.
The main design criteria for libzip
were:
- Do not create corrupt files, even in case of errors.
- Do not delete data.
- Be efficient.
For this reason, when modifying zip archives,
libzip writes to a temporary file and replaces the
original zip archive atomically.
Below there are two sections listing functions: one for how to read from zip archives and one for how to create/modify them.
GENERAL NOTES¶
Unless explicitly documented, functions should not be passed
NULL pointers as arguments.
FILE NAMES¶
Encoding¶
Names of files in the host file system are expected in UTF-8 encoding. On Windows, variants for ASCII and UTF-16 are also available.
Names of files inside archives are by default expected in UTF-8
encoding. Other encodings can be requested by using the flags
ZIP_FL_ENC_CP437 and
ZIP_FL_ENC_RAW.
For details see the relevant man pages.
Directory Separator¶
The zip format requires the use of forward slash
(‘/’) as directory separator. Since backslash
(‘\’) can be part of a valid file name on Unix systems,
libzip does not automatically convert them, even on
Windows. It is the responsibility of the programmer to ensure that all
directory separators are passed as forward slashes to
libzip.
THREAD SAFETY¶
In general, different zip archives opened by
libzip are independent of each other and can be used
by parallel-running threads without locking. If you want to use an archive
from multiple threads, you have to synchronize access to it yourself. If you
use an archive as a source for zip_file_add(3) or
zip_file_replace(3), access to the target archive must be
synchronized with access to the source archive as well.
