Ah, I see. I'm glad you got it. Thanks, Yury Binh-Minh ________________________________ From: Hdf-forum <[email protected]> on behalf of Yury Girshovich <[email protected]> Sent: Thursday, July 25, 2013 4:15 PM To: HDF Users Discussion List Subject: Re: [Hdf-forum] Reading enum bool attribute
Binh-Minh, I made it work. Being a novice HDF5 user, I did not know that I had to use H5Tenum_insert to define the enum datatype. Now everything works. Thanks a lot for your help!!!

I'll keep an eye out for your message with an excerpt of the data file.

I need to ask the owner permission first for sharing the file. Perhaps they can create a very small file just to display the problem. Let me try to separate the code meanwhile, which may take a bit. I'll email it to you with the data asap. I did not use an HDF5 method to find the attribute data type. Are there any? I know the data type from the HDF5 viewer. Here is the relevant portion of my code: The disassembly is attached. . //is_hollow is enum with members {false, true} and value size 1 //bool h, h1, h2; size_t sz1 = attr.getInMemDataSize(); //=1 size_t sz2 = attr.getStorageSize(); //=1 printf("sz1 %d; sz2 %d, szbool %d\n", sz1, sz2, sizeof(bool)); //sz1 1, sz2 1, szbool 1 //the sizes coincide, but each one of those calls crashes. //int i1 = 0; //attr.read(PredType::NATIVE_INT, &i1); //printf("i1 = %d\n", i1); char c1 = 0; attr.read(PredType::NATIVE_CHAR, &c1); // attr.read(PredType::NATIVE_B8, &BB); // attr.read(boolenumtype, &BB); // attr.read(PredType::NATIVE_B8, &h); // attr.read(PredType::NATIVE_UINT8, &h1); // attr.read(PredType::NATIVE_UCHAR, &h2); // printf("is_hollow %d %d %d\n", h, h1, h2); } The error message is: No source available for "raise() at 0x3d66835ba5" The code crashed with all the versions of attribure datatypes.

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?
