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.
