kbhit() for NIOS terminal

[omikron123]

I need an implementation of kbhit() for the nios terminal in eclipse. I found the following example

#include <termios.h>

int kbhit(void)
{
struct termios term, oterm;
int fd = 0;
int c = 0;
tcgetattr(fd, &oterm);
memcpy(&term, &oterm, sizeof(term));
}


i tried but i got an error, so i insertet the function "tcgetattr" directly

#include <termios.h>
#include <sys/ioctl.h>

int
tcgetattr(int fd,struct termios *termios_p)
{
return ioctl(fd,TCGETS,termios_p);
}

-> Now i have the problem, that he can&#39;t find "TCGETS" !! it seems to be defined nowhere ?????

Hi,

Did you solve this non-blocking getch() issue. I have searched and searched to no avail. My next thought would be to create a thread to do it...
Thanks

fcntl() should be supported, non-blocking operations (including getch()) certainly are.
