zip_open

NAME

zip_open, zip_open_from_sourceopen zip archive

LIBRARY

libzip (-lzip)

SYNOPSIS

#include <zip.h>
zip_t *
zip_open(const char *path, int flags, int *errorp);
zip_t *
zip_open_from_source(zip_source_t *zs, int flags, zip_error_t *ze);

DESCRIPTION

The zip_open() function opens the zip archive specified by path and returns a pointer to a struct zip, used to manipulate the archive. The flags are specified by or'ing the following values, or 0 for none of them.
 
 
ZIP_CHECKCONS
Perform additional stricter consistency checks on the archive, and error if they fail.
 
 
ZIP_CREATE
Create the archive if it does not exist.
 
 
ZIP_EXCL
Error if archive already exists.
 
 
ZIP_TRUNCATE
If archive exists, ignore its current contents. In other words, handle it the same way as an empty archive.
 
 
ZIP_RDONLY
Open archive in read-only mode.
If an error occurs and errorp is non-NULL, it will be set to the corresponding error code.
The zip_open_from_source() function opens a zip archive encapsulated by the zip_source zs using the provided flags. In case of error, the zip_error ze is filled in.

RETURN VALUES

Upon successful completion zip_open() and zip_open_from_source() return a struct zip pointer. Otherwise, NULL is returned and zip_open() sets *errorp to indicate the error, while zip_open_from(source) sets ze to indicate the error.

ERRORS

The archive specified by path is opened unless:
 
 
[ZIP_ER_EXISTS]
The file specified by path exists and ZIP_EXCL is set.
 
 
[ZIP_ER_INCONS]
Inconsistencies were found in the file specified by path. This error is often caused by specifying ZIP_CHECKCONS but can also happen without it.
 
 
[ZIP_ER_INVAL]
The path argument is NULL.
 
 
[ZIP_ER_MEMORY]
Required memory could not be allocated.
 
 
[ZIP_ER_NOENT]
The file specified by path does not exist and ZIP_CREATE is not set.
 
 
[ZIP_ER_NOZIP]
The file specified by path is not a zip archive.
 
 
[ZIP_ER_OPEN]
The file specified by path could not be opened.
 
 
[ZIP_ER_READ]
A read error occurred; see errno for details.
 
 
[ZIP_ER_SEEK]
The file specified by path does not allow seeks.
