HDF5 Fortran Required Calls
HDF5 Fortran applications must begin and end, respectively, with the subroutines described below. h5open_f initializes the HDF5 Fortran interface, providing the application with access to the HDF5 library. h5close_f closes the HDF5 Fortran interface without closing the HDF5 library, thereby leaving HDF5 available to other software that may require that resource.
h5open_f
SUBROUTINE h5open_f(error)
INTEGER, INTENT(OUT) :: error
Outputs:
error - Returns 0 if successful and -1 if fails
h5close_f
SUBROUTINE h5close_f(error)
INTEGER, INTENT(OUT) :: error
Outputs:
error - Returns 0 if successful and -1 if fails
HDF5 Fortran Utility Functions
The HDF5 Fortran library offers the following utility functions to facilitate the development of HDF5 Fortran applications.h5offsetof is available only in Fortran 2003 environments; h5kind_to_type and h5gmtime are available in any Fortran environment:
h5offsetof
FUNCTION h5offsetof(start,end) RESULT(offset)
USE, INTRINSIC :: ISO_C_BINDING
USE H5GLOBAL
IMPLICIT NONE
INTEGER(SIZE_T) :: offset
TYPE(C_PTR), VALUE, INTENT(IN) :: start, end
Inputs:
start - starting pointer address end - ending pointer address
Outputs:
offset - offset
h5kind_to_type
INTEGER(HID_T) FUNCTION h5kind_to_type(kind, flag) RESULT(h5_type)
INTEGER, INTENT(IN) :: kind
INTEGER, INTENT(IN) :: flag
Inputs:
kind - Fortran KIND parameter
flag - Whether KIND is of type INTEGER or REAL:
H5_INTEGER_KIND - integer
H5_REAL_KIND - real
Outputs:
h5_type - Returns the type
h5gmtime
Purpose:
Convert time_t structure (C) to Fortran DATE AND TIME storage format.
Signature:
FUNCTION h5gmtime(stdtime_t)
INTEGER(KIND=TIME_T), INTENT(IN) :: stdtime_t
INTEGER, DIMENSION(1:8) :: h5gmtime
Inputs:
stdtime_t - Object of type time_t that contains a time value
Outputs:
datetime - A date/time array using Fortran conventions:
datetime(1) = year
datetime(2) = month
datetime(3) = day
datetime(4) = 0 ! time is expressed as UTC (or GMT timezone) */
datetime(5) = hour
datetime(6) = minute
datetime(7) = second
datetime(8) = millisecond -- not available, assigned - HUGE(0)
