[Oberon] call ioctl() function in linux from AOS

[Jörg Straube]

Hi Zdenek

Try something like the follwing small snippet.
You of course have to adopt the portname and the io functions you want to call.

MODULE test;

IMPORT Unix;

PROCEDURE Do*;
  VAR
     portname: ARRAY 16 OF CHAR;
     fd: LONGINT;
     err: LONGINT;
     result: LONGINT;
  BEGIN {EXCLUSIVE}
     portname := "/dev/ttyS1"; fd := 0;
     fd := Unix.open(ADDRESSOF(portname), Unix.rdwr, {});
     err := Unix.ioctl(fd, Unix.FioRead, ADDRESSOF(result))
  END Do;

BEGIN
END test.Do
