h5aread_f

Hi
I am trying to read an attribute (N_Number_Of_Scans) that has the
following path in the hdf file

/Data_Products/TAMS-SDR/TAMS-SDR_Gran_0/N_Number_Of_Scans

I use the following commands
use h5df
CALL h5dopen_f(file_id, "/Data_Products/TAMS-SDR/TAMS-SDR_Gran_0", dset_id,
error)
print *,"DSET ID Gran`", dset_id
CALL h5aopen_name_f(dset_id,"N_Number_Of_Scans", attr_id, error)
CALL h5aread_f(attr_id, H5T_NATIVE_INTEGER, aread_data,ndata_dims , error)

But I get the error
CALL h5aread_f(attr_id, H5T_NATIVE_INTEGER, aread_data,ndata_dims , error)
                                                                           1
Error: There is no specific subroutine for the generic 'h5aread_f' at (1)

Any help

Can you show me how you declared your arguments in h5aread_f. Are you using any compile flags to promote any integers or reals?

Thanks,
Scot

Hi Scot,

The attribute I wish to read is

ATTRIBUTE "N_Number_Of_Scans" {
               DATATYPE H5T_STD_I32BE
               DATASPACE SIMPLE { ( 1, 1 ) / ( 1, 1 ) }
               DATA {
               (0,0): 12
               }

Is that an array of dim(1,1) ? or a scalar?
I use

Integer :: ndata_dims, aread_data,error

CALL h5aread_f(attr_id, H5T_NATIVE_INTEGER, aread_data,ndata_dims , error)

Hi Scot,
No I am not using any flags to promote the variables.
I use
/data/starfs1/libs/hdf5-1.8.13/bin/h5fc
on a x86_64 x86_64 x86_64 GNU/Linux

Couple of things, you should be declaring:

INTEGER(HID_T) :: attr_id

For reading to an array:

INTEGER(HSIZE_T), dimension(2) :: ndata_dims = (/1,1/)
INTEGER, DIMENSION(1,1) :: aread_data

Or you can read it into a scalar,

INTEGER(HSIZE_T), dimension(1) :: ndata_dims = (/1/)
INTEGER :: aread_data

Either way, ndata_dims always needs to be an 1D array.

You can also forgo f90 and use f2003 instead:

TYPE(C_PTR) :: f_ptr
INTEGER, target :: aread_data

f_ptr = C_LOC(aread_data)
CALL h5aread_f(attr_id, H5T_NATIVE_INTEGER, f_ptr , error)
