I got a note from a Linux developer who is looking for a FreeBSD
equivalent for a Linux feature. The feature allows a program to prevent
others from opening a /dev/ttypx without having to change the permissions
on it. This means the program does not have to be suid root.
In Linux this can apparently be done with:
int flag = 1;
if (ioctl(fd,TIOCSPTLCK,&flag)) // prohibit opening tty from now on
perror("cannot set secure");
Is there any equivalent in FreeBSD? I know TIOCSPTLCK does not exist
in any header I could find in 3.0.
