ZIP_FDOPEN(3)

NAME
zip_fdopen - open zip archive using open file descriptor

LIBRARY
libzip (-lzip)

SYNOPSIS
#include <zip.h>

struct zip * zip_fdopen(int fd, int flags, int *errorp);

DESCRIPTION
The zip archive specified by the open file descriptor fd is opened and a pointer to a

struct zip, used to manipulate the archive, is returned. In contrast to zip_open(3), using the archive can only be opened in read-only mode. The fd argument may not be used any longer after calling The 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.

If an error occurs and errorp is it will be set to the corresponding error code.

RETURN VALUES
Upon successful completion zip_fdopen returns a

struct zip pointer, and fd should not be used any longer, nor passed to close(2). Otherwise, NULL is returned and *errorp is set to indicate the error. In the error case, fd remains unchanged.

ERRORS
The file specified by fd is prepared for use by libzip(3) unless:

    [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 flags argument is invalid. Not all zip_open(3) flags are allowed for see DESCRIPTION.

    [ZIP_ER_MEMORY]
        Required memory could not be allocated.

    [ZIP_ER_NOZIP]
        The file specified by fd is not a zip archive.

    [ZIP_ER_OPEN]
        The file specified by fd could not be prepared for use by libzip(3).

    [ZIP_ER_READ]
        A read error occurred; see for details.

    [ZIP_ER_SEEK]
        The file specified by fd does not allow seeks.
