I do not see a problem with that function. Since your first function seems to work, it is more probable that the error is there. My guess is that the function you posted is never even invoked. After the first function sorts your file, what else does it do? What happens between the first function call and the second function call? Does any module include termio.h or termios.h? Anything requiring them could be the problem. And you of course have searched for an explicit call to ioctl(), right?
I checked the code and there is no place i am connecting to tty. Though many functions are there to fprintf writing to stderr.
I am not using ioctl function anywhere. neither i used termio.h or termios.h.
To answer vergesh question, i double checked for path invoking anothe sort. So there is no possibility this could be a reason.
I will like to go with Perderabo statment that somewhere before itself the errno is getting reset to some error value and when during the call to function sortTempInputfile we first trap to check errno we exit.
Please let me know if there exists any other reasons for ioctl error thrown by unix?
