.. us.tag  nc_endef ENGLISH NC

:ref:`nc_endef` takes an open nc file out of define mode. The changes made to the
nc file while it was in define mode are checked and committed to disk if no
problems occurred. In particular, non-record variables are filled with their
fill-values unless :ref:`nc_setfill` has been called with the argument
``NC_NOFILL``. The nc file is then placed in data mode, so that variable data can
be read or written.

.. function::  r = nc_endef(ncid)

.. us.return

If the function succeeds, the return value is not equal to -1. If the function
fails, the return value is -1.

.. us.params
