Since stdout is by default opened as a text mode file, and is also set to be line buffered, the '\n' at the end of each line automatically causes an fflush(.) and adding another won't help. > The stdio functions use buffered output, so it's likely that zenity is just > not getting any of the output until the program has completed.

Well, what you say is true, but the fflush(.) is going to happen, anyway. If adding one causes a difference in behavior, then you have a non-conforming implementation (i.e., it isn't C).

You have found the bank of Larn. I can explain it for you, but I can't understand it for you. I speak only for myself, and I am unanimous in that!
