[ctypes-users] accessing a C struct

[Jim V. <Jim...@no...>]

Hello,

I am just starting to use the ctypes module.

A function in a dll, being accessed via ctypes, returns the address of a
C
structure.

How can I use this address, from Python, to access fields in the
structure?

Do I define a ctypes Structure for the C structure?  If so, how do I set
the return type of the C function to be this ctypes Structure?

The reason I'm asking rather than trying it is that the C structure is
quite complex (contains nested structures and unions) and so will
require alot of time to specify as a ctypes Structure -- especially if
that is the wrong approach.

Thanks.
