Message: [QUOTE="Jordan Abel, post: 2453370"] My interpretation is the opposite - that it's intended to change stdin to be _another file_ open in read mode, or stdout/stderr to another file open in write mode. It's also possible that on some systems extra magic may be needed to make a re-opened stdout become the standard output of a command executed via system(), or even for a re-opened stream to become the standard stream used by functions not implemented in standard C such as perror(). It also might be desirable for the buffering state of a stream to be retained in some cases. For example, there is a good reason why stderr is not fully buffered at program start. (It's unclear to me whether freopen can even change the buffering state at all - though it could be desirable to do so when changing stdout to be a regular file when it was an interactive device at program startup) [/QUOTE]
