 (2) Put that structure into an array that will be passed to fortran in:
         (a) fortran/src/H5_f.c (add to nh5init_flags_c subroutine)
         (b) edit fortran/src/H5f90proto.h and edit nh5init_flags_c interface call
-                         
+
 (3) Edit the function call in fortran/src/H5_ff.F90
-        (a) edit the call:  FUNCTION h5init_flags_c 
+        (a) edit the call:  FUNCTION h5init_flags_c
         (b) edit h5init_flags_c call in h5open_f to match the number of arguments passing
-                             
-(4) add the size of the array and array to fortran/src/H5f90global.F90

+(4) add the size of the array and array to fortran/src/H5f90global.F90
          - must match the size found it H5_f.c
 
-NOTE: To just add a default C value argument, do steps (2a) and (4)
