! NAME
!  MODULE H5GLOBAL
!
! FILE
!  src/fortran/H5f90global.F90
!
! PURPOSE
!  This module is used to pass C stubs for H5 Fortran APIs. The C stubs are
!  packed into arrays in H5_f.c and these arrays are then passed to Fortran.
!  This module then uses EQUIVALENCE to assign elements of the arrays to
!  Fortran equivalent C stubs.
!
! NOTES
!  The size of the C arrays in H5_f.c has to match the values of the variables
!  declared as PARAMETER, hence if the size of an array in H5_f.c is changed
!  then the PARAMETER of that corresponding array in Fortran must also be changed.
!
! USES
!  H5FORTRAN_TYPES 	 - This module is generated at run time. See
!
