kbhit() in C

[Altera_Forum]

Hi,  

 I searching for an implementation of kbhit() from <conio.h> in C. I want to use this function for the Terminal in the eclipse IDE.    http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif Thx a lot for your help

I&#39;m not sure if i understand you correctly but take a look at the "Board Diagnostics"-Template in Nios II IDE. There is a function called getchar() used for this.

Hi cece, 

 Thx for your answere. But getchart don&#39;t solve my problem, because its a blocking function. This means, if no key is pressed, the function getchar blocks until a key is pressed. With kbhit it is possible just to test, if an key was pressed(without blocking).   -> with the help of <termios.h> it should be possible to programm a kbhit function, but the functions :  - tcgetatt  - tcsetattr  from termios.h doesnt&#39;t work ??? Any other solutions are welcome    Here the code :  int getch()  {  static int ch = -1, fd = 0;  struct termios neu, alt;  fd = fileno(stdin);  tcgetattr(fd, &alt);  neu = alt;  neu.c_lflag &= ~(ICANON|ECHO);  tcsetattr(fd, TCSANOW, &neu);  ch = getchar();  tcsetattr(fd, TCSANOW, &alt);  return ch; }  int kbhit(void)  {  struct termios term, oterm;  int fd = 0;  int c = 0;  tcgetattr(fd, &oterm);  memcpy(&term, &oterm, sizeof(term)); }
