kbhit() for NIOS terminal

[Altera_Forum]

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  Simon

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