zip_open, zip_open_from_source - open zip archive
LIBRARY
libzip (-lzip)
SYNOPSIS
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 corre‐
sponding 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_CRE‐
ATE 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.
