Hi Krishna,

Basically, if you are working in the AST level, i.e., without exposing any
UI, Sergey's suggestion should work. This is what I am working too at the
moment.

Have a look in this minimal (toy) example. I hope it helps you.

       protected void addNewFunction(String name){
	         try {
                         //find node of interest
		         IASTNode node = ASTUtilities.findNodeInTree(mainAST, 1,
Class.forName("org.eclipse.cdt.core.dom.ast.IASTFunctionDeclarator"),
"getName", "test");

			if (node != null && node instanceof IASTFunctionDeclarator){
				//get the rewriter
				ASTRewrite rewriter 		= ASTRewrite.create(mainAST);
				//get the factory
				ICPPNodeFactory nodeFactory =
(ICPPNodeFactory)mainAST.getASTNodeFactory();
				
				//create a new ASTFunctionDefinition
				IASTNode n 	= nodeFactory.newFunctionDefinition(
	
((IASTFunctionDefinition)node.getParent()).getDeclSpecifier().copy(CopyStyle.withoutLocations),
	                       
nodeFactory.newFunctionDeclarator(nodeFactory.newName(name)),				   
                            
((IASTFunctionDefinition)node.getParent()).getBody().copy(CopyStyle.withoutLocations)
						  );

				 //specify its position in the ast
				rewriter.insertBefore(node.getParent(),
node.getParent().getChildren()[0], n, null);

				//ask the rewriter to suggest a change
				Change c = rewriter.rewriteAST();
				
				//make the change
				c.perform(new NullProgressMonitor());				
			}			
		} 
		catch (ClassNotFoundException e) {
			e.printStackTrace();
		}
	}
