Module netcdf4_nc_interfaces

! Fortran interfaces to netCDF4 C functions using FORTRAN 2003 C 
! Interoperability features. These interfaces are for the base
! netCDF C routines in the libsrc4 directory and the results from
! running CPP on the fort-xxx.c routines to get the cfortran.h
! generated interfaces

! Version 1.: June.  2007 - Initial version - split from ntecdf_nc_interfaces 
! Version 2.: April, 2009 - Interfaces based on netcdf-4.0.1 source         
! Version 3.: April, 2010 - Interfaces based on netcdf-4.1.1 source         
! Version 4.: Aug,   2013 - Added nc_rename_grp interfaces for netcdf-C 4.3.1
! Version 5 : Jan.   2016 - General code cleanup  and added interfaces for 
!                           three new funcions in nf_lib.c that return
!                           the number of groups, types, and dimids for
!                           compound fields
                            
 USE netcdf_nc_interfaces

 Implicit NONE

!--------- Define default C interface parameters from netcdf.h ---------------

! Begin explicit interfaces for nc_ functions. Note that some interfaces
! expect data to be passed as C_PTR type variables. These data are arrays
! that could have a NULL pointer passed instead of the array. Also, note
! the use of generic interfaces to support routines that handle text data
! to allow text to be passed as either a single string or an array of
! single characters

! Also note that each interface has an explicit USE ISO_C_BINDING. A better
! solution is to use the F2003 IMPORT statement (I originally had it this way)
! However its best to leave the interfaces as is for now because there might
! be a few compilers out there that support most of the C-interop facility but
! for some reason haven't implemented IMPORT yet.
