[ldns-users] Python rdf.data()

[Karel Slany]

Greetings,

Python's ldns_rdf.data() creates a thin wrapper around the ldns C
function ldns_rdf_data(). Function ldns_rdf_data() returns a pointer to
an internal data field of the manipulated rdf.

Actually, I don't know the actual reason why you are trying to access
this low level structures. Manipulating them from Python can be tricky
as you can easily end up with corrupted memory.

In order to meet your desire I can add a new method ldns_rdf.data_str()
which would return a Python string containing copy of the rdf data
field. However, in Python3 this would be error-prone, because Python3
uses unicode strings. At the moment I cannot guess, whether the approach
would be reliabe in Python3.

Please give more information about the reason why you want to use
ldns_rdf.data(). Perhaps we could think of a more convenient solution.

K.
