Hi all,
Please show us a C/C++ code example that initializes HDF5 objects from
in-memory data without using/opening any files.
Our applications needs to be run very fast and we cannot afford the
transfer to file just so hdf5 can process it.
Basically we want to do:
void* buffer;
int buffer_size
// initialize buffer
file = H5Fcreate(...)
H5F_write_binary_data_to_file(file,buffer,buffer_size)
// read the contents
dataset = H5Dopen(file, DATASETNAME);
...
thank you,
rosen,

You probably want to look into the "core" file driver: H5Pset_fapl_core().

hi Quincey,
We have looked into the core driver, my question was, what are the API
calls to make in order to initialize it with the raw hdf5 data from
memory.
We just want a small snippet of code to show us how to do this.......
any language would do
thank you,

Ah! Unfortunately, we don't support this currently. It is in our ticket system and will get scheduled for implementation according to it's relative priority against other tickets. Of course, funding for implementing the feature or high-quality patches are welcome.
