they will not be removed just like that, they will be replaced by
'good functions' with the same intention as the current non
supported / non documented functions. In other words, not exporting
the functions now, would cause the users to have no way but
duplicating rrdtool code somehow or compiling an alternete version
... in 1.4 they will have the option to switch to the supported

that __attribute__((deprecated)) thing looks cool. How does it
work ? can you send a patch ?
There is another issue with documenting the 'exported /
non-supported' functions, they depend on rrd-format.h which means
that rrd-format.h would have to become an exported header which is
realy not what I intend ...

I think I understand your intention. You want things (however they
are) in the open.
