GM_GetLineFeatureEx

Returns the line feature at the given index in the layer. Returns NULL if the layer does not contain a line at the given index or if a registration key was not found and aLineIndex was greater than GM_MAX_NON_REGISTERED_VECTOR_IDX.

Using the aFlags parameter you can control whether the coordinates for the features are returned in the native projection of the layer or in the current set projection. You can also indicate that you don't want the coordinates at all.

Any features returned from this function must be freed using a call to GM_FreeLineFeature when you are done accessing the the feature.
