You might look at h5copy as a reference, or just use that tool to do the work for you.

(C program) Hello everyone, I am working with an HDF5 file that has a 5D dataset. What I'm wanting to do is to create a C program that reads this dataset into memory and then outputs it into a newly created file with only that dataset in it (perhaps at the root directory of the file tree). What I don't understand is how to read this entire 5D array using H5Dread into a 5D buffer that has been previously allocated on the heap (note I cannot use an array allocated on the stack, it would be too large and would create seg faults). What is the general process I need to employ to do such a thing, and is there maybe a more elegant solution to this than reading the entire dataset into memory? This process seems easy to me for a 1 or 2D array but I am lost with larger dimension arrays. Thanks. Regards, Landon
