[Mapserver-users] mapscript: new functions numMetaData and keyMetaData required

Hi list,

Mapscript currently has no methods to retrieve existing metadata
without knowing its keys. 

Therefore I have written two new methods:
'numMetaData' gets the number of metadata entries (like map->numlayers), 
and 'keyMetaData(pos)' gets the key of the metadata entry on position 'pos'.

To achieve this functionality patching of maphash.c, maphash.h and
mapscript.i is necessary.  The patches are context-diffed against the
mapserver cvs-version of sunday, sept. 21, 2003 and can be downloaded
from

http://dream.lrrl.arch.tu-muenchen.de/~springm/mapserver/maphash_patches/maphash.c.patch
http://dream.lrrl.arch.tu-muenchen.de/~springm/mapserver/maphash_patches/maphash.h.patch
http://dream.lrrl.arch.tu-muenchen.de/~springm/mapserver/maphash_patches/mapscript.i.patch

I hope this patch can be included in the current and future versions of mapserver.
I have filed it as a enhancement request in bugzilla.

Markus
