NAME

       zip_fdopen - open zip archive using open file descriptor

LIBRARY

       libzip (-lzip)

SYNOPSIS

       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_READ]    A read error occurred; see errno for details.

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