Yeah, actually. I was unaware of that particular call. That said, that function is obviously limited to data types and operates on buffers, rather than on streams. At least for the debugging use case, having the output go to a stream would be more useful, IMO, thereby eliminating the overhead of having to allocate and free a temporary buffer.

For now I'll try to remember that function exists should the need come up again.

John,

Do you think this High-Level function H5LTdtype_to_text would help? See http://www.hdfgroup.org/HDF5/doc/HL/RM_H5LT.html#H5LTdtype_to_text ?

It occurs to me that the h5dump program does a lot of stuff that would be really useful to have in library code. As an example, I was running into a problem today that I suspected was due to a type definition that was in use incorrectly. I was ultimately able to confirm my suspicion by reading code, but during that search I thought it'd be really handy to have a function that I could use to dump out the structure of the data type to some output stream or other.

h5dump already does what I was interested in, but it's not library code and would be difficult to integrate into my program to look at the definition of a type that's only defined in memory.

Anyway, I thought it'd be super useful to have some of this code in h5dump moved into a high level library for debugging (or other) purposes.
