void yac_dist_grid_pair_get_corner_cells	(	struct yac_dist_grid_pair *	grid_pair,
		char const *	grid_name,
		size_t *	vertices,
		size_t	count,
		size_t **	vertex_to_cell,
		size_t *	num_cells_per_vertex
	)

Determines for all provided vertices the cells surrouding them.

Parameters

[in]	grid_pair	distributed grid pair
[in]	grid_name	grid name of the grid on which this routine is supposed to work on
[in]	vertices	local ids of selected vertices
[in]	count	number of entries in vertices
[out]	vertex_to_cell	list of result cells for all vertices associated to the selected cells
[out]	num_cells_per_vertex	number of result cells for each vertex

Remarks

the result cells for a vertex is sorted by their global id

the user is responsible for free the memory of the vertex_to_cell array

the user has to make sure that the array num_cells_per_vertex is at least of size "count"

[in]	to_dist_owner	determines whether the sorting is based on the dist or orig owner of the respective points
