Description
FLDFget_typed_node_data returns an array containing the node data, converted to the desired type.
Parameters
field
The field from which to extract the node data.
comp
Which component to extract.
type
An integer representing the desired data type for node_data. You store the desired type, according to the table below, into type. Possible values are:

size
The size of the returned node_data array is returned in the integer to which this parameter points.
node_data
An integer representing a pointer to the node_data array is stored into node_data. You must call ARRFfree() on the resulting an integer representing a pointer when you are done using it.
On 64-bit platforms dims_ptr is actually an INTEGER*8.
mode
The access mode for the node_data array:
