I assume that you are looking for the layerObj method queryByPoint(). I
don't have an example for you though.
David.
queryByPoint( mapObj
<http://mapserver.gis.umn.edu/docs/reference/mapscript/index_html#mapobj
> map, pointObj
<http://mapserver.gis.umn.edu/docs/reference/mapscript/index_html#pointo
bj> point, int mode, float buffer ) : int
Query layer at point location specified in georeferenced map coordinates
(i.e. not pixels). The query is performed on all the shapes that are
part of a CLASS that contains a TEMPLATE value or that match any class
in a layer that contains a LAYER TEMPLATE value. Mode is MS_SINGLE or
MS_MULTIPLE depending on number of results you want. Passing buffer <=0
defaults to tolerances set in the map file (in pixels) but you can use a
constant buffer (specified in ground units) instead. Returns MS_SUCCESS
if shapes were found or MS_FAILURE if nothing was found or if some other
error happened.

I'm stuck and I don't know where to go from here. I need to
search a layer by latitude/longitude, but I don't see this available in
the API. How is this done? What I want to do is take an address, geocode
it to produce the lat/long coordinate, and use it to query my shape
file. I feel I may be missing a step.
