\fBlibzip\fR
\- library for manipulating zip archives
.SH "LIBRARY"
libzip (-lzip)
.SH "SYNOPSIS"
\fB#include <zip.h>\fR
.SH "DESCRIPTION"
\fBlibzip\fR
is a library for reading, creating, and modifying zip archives.
.PP
The main design criteria for
\fBlibzip\fR
were:
.PD 0
.TP 4n
\fB\(bu\fR
Do not create corrupt files, even in case of errors.
.TP 4n
\fB\(bu\fR
Do not delete data.
.TP 4n
\fB\(bu\fR
Be efficient.
.PD
.PP
For this reason, when modifying zip archives,
\fBlibzip\fR
writes to a temporary file and replaces the original
zip archive atomically.
.PP
Below there are two sections listing functions: one for how to read
from zip archives and one for how to create/modify them.
.SS "THREAD SAFETY"
In general, different zip archives opened by
\fBlibzip\fR
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.
