mhdf_createNodeCoords()

hid_t mhdf_createNodeCoords	(	mhdf_FileHandle	file_handle,
		int	dimension,
		long	num_nodes,
		long *	first_node_id_out,
		mhdf_Status *	status
	)

Create new table for node coordinate data.

Parameters

file_handle	The file.
dimension	Number of coordinate values per node.
num_nodes	The number of nodes the table will contain.
first_node_id_out	Nodes are assigned IDs sequentially in the order they occur in the table, where the ID of the first node in the table is this passed-back value.
status	Passed back status of API call.

Returns

An HDF5 handle to the coordinate table.
