All,
Given the dataset I would like to know what are the individual datatypes ( I do not need hid_t for the datatype . I need actual datatype list) that make up the dataset . Is there any API which can do this ?

I assume that you have complex datatypes. I don't know if there is a
more direct way, but what I normally do is, given the type_id, use the
H5Tget_class & H5Tget_size routines:
// Get the HDF5 class
class_id = H5Tget_class(type_id);
// Get the itemsize
itemsize = H5Tget_size(type_id);
and use this info to detect the exact types. For example:
if class_id == H5T_BITFIELD {
stype = "b1";
}
elif class_id == H5T_INTEGER {
// Get the sign
sign = H5Tget_sign(type_id);
if (sign > 0):
stype = "i%s" % (itemsize);
else:
stype = "u%s" % (itemsize);
}
elif class_id == H5T_FLOAT {
stype = "f%s" % (itemsize)
}
elif class_id == H5T_COMPOUND {
...
and so on so forth.
Cheers,
