Hi,
it's easier to have just one contiguous buffer of type char* with a
single allocation for doing the I/O. If your strings are all of fixed
length, you can pack all those independent strings into a single char*
buffer . Then do I/O on that one-dimensional buffer of chars, and when
you need them as strings, you extract them from this char* buffer.

I am reading hdf5 file which has String dataset values with fixed
length size and the number of dimensions is 1. I am using HDF 1.10.1
Windows10 x64.
I allocate array of pointers to read the data values in the same way
as given in the hdf5 documentation. Here is the code which is reading
the string dataset values.
In this code, the dynamic 2D array of pointers is not initialized as
per the standard way using a loop.
unique_ptr<T*[]> apbuffer = make_unique<T*[]>(size_of_dimensions[0]);
T** buffer = dpbuffer.get();
unique_ptr<T[]> apbuffer1 = make_unique<T[]>(size_of_dimensions[0] *
size);
buffer[0] = dpbuffer1.get();
for (int i = 1; i < size_of_dimensions[0]; i++) {
buffer[i] = buffer[0] + i * size_of_dimensions[1];
}
H5Dread(dataset_id, dataset_type_id, H5S_ALL, H5S_ALL, H5P_DEFAULT,
&buffer[0][0]);
I would like to know, what are other possible ways to allocate the
buffer to read 1 dimension string dataset values?
Can we simply read the 1 dimension dataset values by passing arrays
pointed to the buffer?
Any insight is greatly appreciated.
