[issue2712] enhanced ioctl

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

Passing structures is certainly possible. I'd try

args = struct.pack("iP", len(c), cast (pointer (c), c_void_p).value)
fcntl.ioctl(fd, request, args)

Alternatively,

args = eos_dl_args_t()
...
args_p = cast(pointer(args), c_void_ptr).value
fcntl.ioctl(fd, request, args_p)

should also work, IIUC.
