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_handleThe file.
dimensionNumber of coordinate values per node.
num_nodesThe number of nodes the table will contain.
first_node_id_outNodes 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.
statusPassed back status of API call.
Returns:
An HDF5 handle to the coordinate table.
