- Subject: tcsetattr timeout problem ?
Hi all,
I've got a problem with reading a caracter with timeout.
Here is the source file:
The timeout don't seem to be activate.
Thanks.
#include <unistd.h>
#include <stdio.h>
#include <termios.h>
int main ()
{
struct termios new_settings;
struct termios stored_settings;
int timeout=2;
char c;
tcgetattr (0, &stored_settings);
new_settings = stored_settings;
new_settings.c_lflag &= ~(ICANON | ECHO);
new_settings.c_cc[VTIME] = timeout * 10; /* 2secs */
new_settings.c_cc[VMIN] = 0;
tcsetattr (0, TCSANOW, &new_settings);
do
{
printf("character:");
fflush(stdout);
c = getchar ();
printf ("%d\t%c\n", c, c);
}
while (c != 'q');
tcsetattr (0, TCSANOW, &stored_settings);
return 0;
}
