It would be better to avoid the mixed upper/lower case names, since this makes it look like they're win32 api structures. Something like typedef struct region_element region_element is nicer. Same goes for the element names like pathHeader etc.

A better name for numOps would be num_child_nodes. This is the total number of children under the root node (and is equal to twice the number of ops). I should update my comment at the beginning of region.c to reflect this.

How about actually embedding the structure here rather than a pointer to it? Since you'll always have a root node there's no need to allocate it explicitly. And let's call it 'root' not 'node'. Something like region_element root

Are you sure RegionType is in the win32 api? I can't find this is my gdiplusenums.h. If it isn't then it should be put in gdiplus_private.h (or even just in region.c if nothing else uses it) and renamed to enum region_type. Again, I think you'd be better off submitting a couple of patches at a time. Huw. -- Huw Davies huw(a)codeweavers.com
