@kirby @p So that you can backspace when writing input without each program having to write support for it

@kirby Syscall overhead. You can read a single byte from FD 0 if you want.char c; read(0, &c, 1);

@kirby (Also getchar() returns an int rather than a char so be careful with using its output as a subscript.)

@kirby Okay, so you will want to probably do raw mode. If you don't need the character, you can use select() to see if it's there.

@kirby @p use tcsetattr for that: https://stackoverflow.com/questions/3276546/how-to-implement-getch-function-of-c-in-linuxor use ncurses.

@apropos @kirby @p Oh yeah, there are usually two levels of buffering because legacy, both the terminal and libc's FILE*

@eris @apropos @kirby I don't know if it's a legacy thing. The programs are still in separate memory spaces (thus the read is still a syscall), and there are lots of reasons to buffer it locally.

@kirby @apropos You just ask it for a struct from tcgetattr. Probably easiest to just call cfmakeraw() on the result.struct termios attr;tcgetattr(0, &attr);cfmakeraw(&attr);

@kirby @apropos Nah, yer fine, this stuff takes a minute to get your head around. First line allocates a termios named attr because these functions all want one, the second line populates it by asking tcgetattr() to fill in the attributes for FD 0 (stdin), the last line sets raw mode.

@kirby @apropos That bit just sets the terminal to raw mode so that you can read stdin one byte at a time. From there, you should read it with read().You usually don't wanna read stdin one byte at a time but if you want to do that, that is how you do that.

@kirby @apropos Just calls the program that does what you're doing. You should probably do "/bin/stty -raw -echo", actually. It's better to get the cfmakeraw() call to work but this will do in a pinch.You can see what it's actually doing under the hood by doing `strace -vv stty -raw -echo` in the shell. It just calls ioctl() with some special values.
