Weird results when programs are swapped. Message-ID: <193@tekchips.UUCP> Date: Fri, 19-Oct-84 17:59:23 EDT Article-I.D.: tekchips.193 Posted: Fri Oct 19 17:59:23 1984 Date-Received: Mon, 22-Oct-84 06:46:38 EDT References: <91@azure.UUCP>, <192@tekchips.UUCP> Lines: 13 Oops, I found out why the error was ENOTTY after the program swapped; in the original program, an error is detected and errno is printed. But errno is printed in something like the second or third printf, so all bets are off that the value printed is what really caused the error to begin with. If you save the value of errno and then print the saved value, the error is EIO even after swapping, which is what is to be expected. Terry Laskodi of Tektronix
