C++ coding using Panda3D

I have a hidden graphics buffer and want to render a output of a camera to a buffer without rendering it into a main window, the code for python is

mybuffer = base.win.makeTextureBuffer("My Buffer", 512, 512) 
 mytexture = mybuffer.getTexture() 
 mybuffer.setSort(-100) 
 mycamera = base.makeCamera(mybuffer) 
 myscene = NodePath("My Scene") 
 mycamera.node().setScene(myscene)

here i have mycamera = base.makeCamera(mybuffer)
to attach the cam to the buffer i could not find the corressponding statement in cpp can someone direct me to this statement.

Thanks.

You can look in the ShowBase.py source code to see what makeCamera is doing.
