ioctl

Hi,

Is function C_Ioctl in package Gnat.Sockets.Thin equivalent to C's ioctl?

Thanks.

If you're on Windows, I would say C_Ioctl is equivalent to "ioctlsocket", as
you can see in the private section of Gnat.Sockets.Thin.

   pragma Import (Stdcall, C_Ioctl, "ioctlsocket");

The function "ioctlsocket" is part of the standard Win32 API.

(a) it looks like the sort of ioctl you use to get a value (rather
than set it).

I think ioctl is better modelled as a pair of generics (in the type of
the third parameter). You do need a little code in the body, of course
..

(b) not sure you're supposed to be calling the .Thin package ..

My intention is to open a device file in /dev and read the contents from 
the device. I doubt the C_Ioctl function in Gnat.Sockets.Thin is 
equivalent to ioctl of C.
