I'm having some problems getting ncurses' getch() to block. Default operation seems to be non-blocking (or have I missed some initialization)? I would like it to work like getch() in Windows. I have tried various versions of
timeout(3000000); nocbreak(); cbreak(); noraw(); etc...
(not all at the same time). I would prefer to not (explicitly) use any WINDOW
, if possible. A while
loop around getch(), checking for a specific return value is OK too.
Ncurses is a programming library providing an API, allowing the programmer to write text-based user interfaces, Text User Interface (TUI), in a terminal-independent manner. It also optimizes screen changes, in order to reduce the latency experienced when using remote Unix shell.
The curses library is a package deal. You can't just pull out one routine and hope for the best without properly initializing the library. Here's a code that correctly blocks on getch()
:
#include <curses.h> int main(void) { initscr(); timeout(-1); int c = getch(); endwin(); printf ("%d %c\n", c, c); return 0; }
