/** \file \internal
Internal netcdf-4 functions.

This file contains functions internal to the netcdf4 library. None of
the functions in this file are exposed in the exetnal API. These
functions all relate to the manipulation of netcdf-4's in-memory
buffer of metadata information, i.e. the linked list of NC_FILE_INFO_T
structs.
