)  [static]
 

Helper function to create a new NodeSetProperty, with default properties, and attach it to the given node in an undoable way.

Author:

Date:
27/5/99
Parameters:
strName --- the node to 'apply' a property to [INPUTS] pNode --- the property to 'apply' to the node pOp --- the Operation context in which to manipulate nodes pCopyPropNode --- the NodeSetProperty whose properties are to be copied into the 'applied' property, or null for no copy and default properties.
Returns:
Pointer to the newly 'applied' NodeSetProperty, or null for failure.

Errors: Out of memory.
