Hi Yury, Is there any chance I can have a copy of the file and that part of your code, from opening the file, perhaps? I want to repeat the exact steps. If not, please send me the errors.

It was the returned value of the call to attr.getInMemDataSize(). Sorry for the misinformation. The call to: int i; attr.read(PredType::NATIVE_INT, &i) causes a crash. That is not surprising because of the size discrepancy. But I also tried to use all kinds of 8bit creatures, like char, uchar, bool, replacing NATIVE_INT by NATIVE_CHAR, etc., but they all ended up with a crash.

What happens if you try your read with attr_type as a NATIVE_INT and i as an int? Then cast it to bb. Scott From: Hdf-forum [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Yury Girshovich Sent: Wednesday, July 24, 2013 1:04 PM To: [email protected]<mailto:[email protected]> Subject: [Hdf-forum] Reading enum bool attribute I am trying to read an attribute defined as typedef enum {bbo=false, bb1=true} bb; as bb i; attr.read(attr_type, &i); The size of the attribute value is 1 byte. For attr_type I tried all kinds of 8 bit predicate types (as one advice suggested use int, and then interpret your data), bur no matter what I do the code crashes. The value is inserted in a different code using Python, so I can get no help from there. How should I define the predicate type then?
