Hi, I use FpIOctl from "BaseUnix" . My platform is Linux. I do FpOpen then FpIOCTL. It works!
However: The kernel 2.6 has a new naming convention for the function number. See the file: asm/ioctl.h This file contains many constants and the final call number is assembled from the direction type, device number, function number, etc... I wanted to write a unit that would simulate this file (ioctl.h), but, this header file contains mainly macros. I do not think that it is possible to write some Pascal code that would in fact be a macro! If someone knows if it possible to write macros in Pascal please tell me. In the mean time, I calculate the function number "by hand", knowing the device number, function number, IO_RW, etc... Or if I use a precedure do do this, then this will slow the program down. For the Windows platform, I can not help you sorry.
