Dear Forum members,
I am trying to read an integer attribute in an hdf5 file. H5aread_f
shows following error:
HDF5-DIAG: Error detected in HDF5 (1.8.8) thread 0:
#000: ../../hdf5-1.8.8/src/H5A.c line 1079 in H5Aread(): not a datatype
major: Invalid arguments to routine
minor: Inappropriate type
Source code is:
c#######################################################################
subroutine read_hdf5(h5filename)
c#######################################################################
use hdf5
implicit none
integer :: hdferror
integer(hid_t) :: file_id,attr_id,grp_id,atype_id
integer(hsize_t), dimension(1) :: adims
integer, dimension(1):: attr_data
character(len=*) :: h5filename
c--- open hdf5 - file
call h5fopen_f(h5filename,H5F_ACC_RDWR_F,file_id,
& hdferror)
call h5gopen_f(file_id,'/Mesh/Elements',grp_id,hdferror)
call h5aopen_f(grp_id,'Num2DElems',attr_id,hdferror)
adims(1) = 1
call h5aread_f(attr_id,H5T_NATIVE_INTEGER,attr_data,
& adims,hdferror)
write(*,*) 'Num2DElems: ', attr_data(1)
call h5aclose_f(attr_id,hdferror)
call h5gclose_f(grp_id,hdferror)
call h5fclose_f(file_id,hdferror)
end subroutine read_hdf5
It seems to be an easy error, sorry. I hope anyone can help. I am stuck
with this problem ...
Best regards,
Matthias
