Randy,
I do not use s57 data, however I have written a number of programs which use
OGR_FD_GetName ... and it has always returned the feature name, if set, or null
for me. Feature, as opposed to Layer, names seem quite uncommon, however;
although I generally set feature names when creating data objects, I have rarely
encountered them on input from other sources. I have never investigated whether
this is a failure in OGR to transmit the name or whether my presumption that
there was no name to transmit is correct.
I'm not sure how much that helps,
Peter

Hi Chaitanya,
Thanks for your quick response!
I use this function in parse a s57 file(*.000). In this format file,I
think the layer-name in OGR should be like this:
berths,bridge,canals...
which to some extend,is as same as a feature-name. But now I'm not sure
whether I understand this concept right or not?
In my application,OGR_FD_GetName()returns:
DSID
Point
Line
Area
Meta
I'd like to know whether this function works fine or not? If yes, how
should I get a feature's name?
Thanks a lot!
Best regards,
Randy
OGR_FD_GetName() returns the name of the feature definition set during
it's creation. It doesn't have to be unique and doesn't represent the
object type or geometry type. It is not affected by any environment
variables.

Hi list,
I reinstalled my OS (Ubuntu10.04) recently and now the
OGR_FD_GetName
function results in "layername" with
"point,Line,Area,Meta",but I
believe this function could get a layer's object name but not
its
geometry type.
I'm not sure the problem exist in environment variable or not
and, if
so, what are they?
Best regards
Randy
