getpt() opens a pseudoterminal master always returns 0
Issue
We use getpt () to open the pseudo terminal master. In one of our applications this always returns 0.
Strace traces also showed the same:
open("/dev/ptmx", O_RDWR) = 0
Code snippet:
fd = getpt (); // open the pseudo terminal master
if (fd >= 0) {
..
}
else {
return "Could not get pseudo terminal";
}
On the live system we are going into the else part. Please let me know why the api is returning 0.
