Currently you can only use the high level functions for reading the
default integer type (i.e. 4 bytes or if -i8, 8 bytes) since the input
buffer is declared
INTEGER, INTENT(inout), ..... :: buf.
The lower level function h5dread_f also only supports reading the
default integer for the same reason.
There is a Fortran 2003 hdf5 function for h5dread_f where the call
would be:
USE ISO_C_BINDING
TYPE(C_PTR) :: f_ptr
f_ptr = C_LOC(umesh%elements(1))
CALL H5Dread_f(dataset, H5T_NATIVE_INTEGER_1, f_ptr, error)
but it's currently only available in a development branch and only for
the lower level functions.
BTW, kind=1 is not standard since it's up to the compiler vendor to
determine if kind=bytes or not, you should select the integer kind using
selected_integer_kind, which will also tell you if integer*1 is available.

Hello,
I try to use the function h5ltread_dataset_f to read a integer(kind=1)
array.
An example of my code is at :
https://code.google.com/p/amelet-hdf/source/browse/amelethdf-fortran/trunk/src/amelethdf/unstructuredmesh.f90#107
I have to read values in a temporary integer(kind=4) array otherwise the
compiler says there is no function to read the dataset :
! Elements definition
type unstructured_mesh_t
...
integer(kind=1), dimension(:), allocatable :: elements
...
end type unstructured_mesh_t
....
! Elements reading
integer, dimension(:), allocatable :: tmpelements
allocate(umesh%elements(one_dims(1)))
allocate(tmpelements(one_dims(1)))
call h5ltread_dataset_f(file_id, path, H5T_NATIVE_INTEGER_4,&
tmpelements, one_dims, hdferr)
umesh%elements = tmpelements
deallocate(tmpelements)
I thought I could write :
call h5ltread_dataset_f(file_id, path, H5T_NATIVE_INTEGER_1,&
umesh%elements, one_dims, hdferr)
Is there anything I do wrong ?
I use HDF5 1.8.6 with ifort under Linux Ubuntu 10.04
Thanks a lot,
Best regards,
Cyril.
