H5P_ENCODE encodes the property list
plist_id into the binary buffer
If the required buffer size is unknown,
buf can be passed in as
NULL and the function will set the required buffer size in
nalloc. The buffer can then be created and the property list encoded with a subsequent
If the buffer passed in is not big enough to hold the encoded properties, the
H5Pencode call can be expected to fail with a segmentation fault.
Properties that do not have encode callbacks will be skipped. There is currently no mechanism to register an encode callback for a user-defined property, so user-defined properties cannot currently be encoded.
Some properties cannot be encoded, particularly properties that are reliant on local context.
