Module netcdf4_nf_interfaces

! Explicit interfaces for Netcdf4 FORTRAN 2003 nf FORTRAN interface routines

! We exclude functions for netCDF4 that pass data of any type to/from void
! pointers in C using a C_CHAR string array. We do provide external statements
! for these routines

! Version 1. April 2009 - Initial module based on netCDF 4.0.1 interfaces
!                         A separate module is required to avoid a
!                         module dependency problem
! Version 2. April 2010 - Updated to Netcdf 4.1.1
! Version 3. Aug.  2013 - Made nf_def_var_fill and nf_inq_var_fill external
!                         to support new nf90_ non-integer fill characters
!                         Added interface for new nf_rename_grp function 
!                         Changed interface type defs to USE netcdf_nf_data
! Version 4. Jan.   2016  General code cleanup

! Most legacy programs don't need to use this module. However, I've created
! it to support FORTRAN programmers who like to provide explicit interfaces
! for all subroutines and functions in their codes. Therefore, this module is
! is primarily for people writing new programs.
