ZIP_FDOPEN(3)              Library Functions Manual              ZIP_FDOPEN(3)

NAME
     zip_fdopen - open zip archive using open file descriptor

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #include <zip.h>

     zip_t *
     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 zip_fdopen the archive can only be opened
     in read-only mode.  The fd argument may not be used any longer after
     calling zip_fdopen.  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.

     If an error occurs and errorp is non-NULL, 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 zip_fdopen, 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_OPNOTSUPP]
                        This functionality has been disabled at compile time.

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

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