bionic (3) zip_open_from_source.3.gz

NAME

       zip_open, zip_open_from_source - open 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.
