template<typename INT >

bool GEOfindAttrib	(	const GA_Attribute *	queryattrib,
		const GA_Range &	queryrange,
		const GEO_Detail &	searchindetail,
		const GA_Range &	searchinrange,
		const GA_Attribute *	searchinattrib,
		const GA_RWHandleT< INT > &	foundprimnums,
		const GA_RWHandleV3 &	foundprimuvws,
		float	tolerance = 1e-7f,
		bool	wrapunitcube = false
	)

Finds, for each element in queryrange, the primitive number and primitive uvw in searchindetail at which searchingattrib matches queryattrib.

If appropriate, it interpolates inside (convexed) polygons and tetrahedra to find matching values. Anything that has no match will not be written-to, in case you want to do multiple queries, so make sure to initialize foundprimnums to -1 (default value -1 suffices).

Returns false if the attributes aren't compatible with this querying. searchinattrib must be a numeric, float, point or vertex attribute, queryattrib must be a numeric, float or int attribute of any owner, and the two must have the same tuple size. searchinrange must be a primitive range.

	)

Finds, for each element in queryrange, the vertex or point numbers and corresponding weights in searchindetail at which searchingattrib matches queryattrib.

If appropriate, it interpolates inside (convexed) polygons and tetrahedra to find matching values. Anything that has no match will not be written-to, in case you want to do multiple queries, so make sure to initialize foundprimnums to -1 (default value -1 suffices).

With this version, for polygons with 5 or more sides, only up to 4 indices and weights are produced, because it considers the convexed polygons produced by GEOconvexPoly, producing results more consistent with Mantra.
