Re: [ctypes-users] Using ctypes to to build a pointer(pointer(struct))

[Nathan H. <iwa...@go...>]

Hi all,

I m currently trying to wrap some "wtf" c code with ctypes and have the
current problem:

one of the methods takes a POINTER(POINTER(Model)) as an argument and I
currently have want to pass a list of models to this function, which are
defined like this:

models = [ Model(), Model() ]

so i convert l to a ctypes list using:

m = ( Model  * len(models))( *models )

which unfortunately doesnt work (obviously).
sim.foo(m)

Is there an easy way that I can convert an list of models into
POINTER(POINTER(Model) using Python, or would it be best to write a wrapper
function in C to accomplish this (which doesnt appeal to me at all) as I
have access to the C code.

Many Thanks in advance

Nathan

PS. I don't know why the original author used POINTER(POINTER(Model)) when
POINTER(Model) would have sufficed.
