Dear all
I wanted to implement the ioctl syscall for X86.
Can any of you please help me with that ?
Should I use a similar implementation as shown below or is it somehow
incomplete?
if (fd < 0 || process->sim_fd(fd) < 0) {
// doesn't map to any simulator fd: not a valid target fd
return -EBADF;
}
switch (req) {
case OS::TIOCISATTY_:
case OS::TIOCGETP_:
case OS::TIOCSETP_:
case OS::TIOCSETN_:
case OS::TIOCSETC_:
case OS::TIOCGETC_:
case OS::TIOCGETS_:
case OS::TIOCGETA_:
case OS::TCSETAW_:
return -ENOTTY;
default:
fatal("Unsupported ioctl call: ioctl(%d, 0x%x, ...) @ \n",
fd, req, tc->pcState());
}
appreciate your help in advance
