I'm trying to write a program like ``more.'' How can I get back to the interactive keyboard if stdin is redirected?

✍: Guest

There is no portable way of doing this. Under Unix, you can open the special file /dev/tty. Under MS-DOS, you can try opening the ``file'' CON, or use routines or BIOS calls such as getch which may go to the keyboard whether or not input is redirected.

Once I have used freopen, how can I get the original stdout (or stdin) back?
Once I have used freopen, how can I get the original stdout (or stdin) back? There isn't a good way. If you need to switch back, the best solution is not to have used freopen in the first place. Try using your own explicit output (or input) stream variable, which you can reassign at will, while leav... 2015-10-01, 1001👍, 0💬

How can I read a binary data file properly?
How can I read a binary data file properly? I'm occasionally seeing 0x0a and 0x0d values getting garbled, and I seem to hit EOF prematurely if the data contains the value 0x1a. When you're reading a binary data file, you should specify "rb" mode when calling fopen, to make sure that text file transl... 2015-09-24, 981👍, 0💬

How can I change their mode to binary?
I'm writing a ``filter'' for binary files, but stdin and stdout are preopened as text streams. How can I change their mode to binary? There is no standard way to do this. On Unix-like systems, there is no text/binary distinction, so there is no need to change the mode. Some MS-DOS compilers supply a... 2015-09-21, 971👍, 0💬

I am trying to update a file in place ...
I'm trying to update a file in place, by using fopen mode "r+", reading a certain string, and writing back a modified string, but it's not working. Be sure to call fseek before you write, both to seek back to the beginning of the string you're trying to overwrite, and because an fseek or fflush is a... 2015-10-07, 948👍, 0💬

How can I arrange to have output go two places at once, e.g. to the screen and to a file?
How can I arrange to have output go two places at once, e.g. to the screen and to a file? You can't do this directly, but you could write your own printf variant which printed everything twice. Here is a sample logprintf function which prints to both stdout and a preopened log file: #include &lt... 2015-09-29, 910👍, 0💬

What is the difference between text and binary I/O?
What is the difference between text and binary I/O? In text mode, a file is assumed to consist of lines of printable characters (perhaps including tabs). The routines in the stdio library (getc, putc, and all the rest) translate between the underlying system's end-of-line representation and the sing... 2015-09-21, 909👍, 0💬

How can I tell if standard input or output is redirected
How can I tell if standard input or output is redirected (i.e. whether ``<'' or ``>'' was used on the invocation command line)? You can't tell directly, but you can usually look at a few other things to make whatever decision you need to. If you want your program to take input from std... 2015-10-01, 904👍, 0💬

How can I recover the file name given an open stream?
How can I recover the file name given an open stream? This problem is, in general, insoluble. Under Unix, for instance, a scan of the entire disk (perhaps involving special permissions) would theoretically be required, and would fail if the descriptor were connected to a pipe or referred to a delete... 2015-10-05, 903👍, 0💬
