Get/Check type of attribute

[Flamefire]

Is there currently any way to check the type of an attribute?
I currently see only the interface readAttribute(int32_t id, const char *dataName, const char *attrName, void* data) which completely ignores the type. So reading a double when a float was expected leads to buffer overflows. Even worse for unexpected array attributes.

Especially for multidimensional values this is a problem. You cannot read a value, that may have multiple dimensions as you don't know how many values are in the HDF5 file.
