Hi everyone,
My final post for today, I hope :-P
One of my binaries needed an unimplemented ioctl command code (TCSETAW).
This patch adds it.
However, I have a question about these codes and their names. At least
in the kernel I'm looking at (2.6.15), there isn't a TIOCGETA or a
TIOCGETS which are used in sim/syscall_emul.hh . However, there is a
TCGETA and TCGETS which I believe is what is meant. Are these names
wrong and should I change them? (Presumably this would require changing
all ISAs?)
Cheers
Tim
