The following code works on linux:
include <termios.h>
using namespace std;
static struct termios old_terminal_settings;
void setterm() {
tcgetattr(STDIN_FILENO, &old_terminal_settings);
// Set terminal to unbuffered input mode
struct termios new_terminal_settings = old_terminal_settings;
new_terminal_settings.c_lflag &= ~ICANON;
tcsetattr(STDIN_FILENO, TCSANOW, &new_terminal_settings);
}
void resetterm() {
// Restore the original terminal settings
tcsetattr(STDIN_FILENO, TCSANOW, &old_terminal_settings);
}
int main() {
int c;
setterm();
while (c = getc(stdin)) {
putc(c, stdout);
}
resetterm();
return 0;
}
When compiled under msys2 with:
g++ -g -I/usr/include term.cc
it fails to link. I can't find any library with the missing symbols:
tcgetattr
tcsetattr
I tried:
nm /usr/lib/*.a | grep tcgetattr
nm /mingw64/lib/*.s | grep tcsetattr
Since there is an include file termios.h I assume there must be a library with the corresponding symbols? If so, how?
If not, is there anything else I can do?
I found a symbol containing the name _nc_term_tcgetattr and tcsetattr in libncurses.a in /mingw64/lib but it's only part of the curses package. Presumably to use it I would have to use curses.
