Thread: A very SIMPLE program that is IMPOSSIBLE to create on Mac!

@Salem I have specified above that the code presented in my message is the exact same as in the previous message before main(). There it is if you like:

Code:

#ifndef GETCH_H_INCLUDED
#define GETCH_H_INCLUDED


#include <stdio.h>
#include <termios.h>
#include <unistd.h>
#include <fcntl.h>


int ch;
unsigned long wait=0;


int kbhit(void)
{
  struct termios oldt, newt;
  int oldf;


  tcgetattr(STDIN_FILENO, &oldt);
  newt = oldt;
  newt.c_lflag &= ~(ICANON | ECHO);
  tcsetattr(STDIN_FILENO, TCSANOW, &newt);
  oldf = fcntl(STDIN_FILENO, F_GETFL, 0);
  fcntl(STDIN_FILENO, F_SETFL, oldf | O_NONBLOCK);


  ch = getchar();


  tcsetattr(STDIN_FILENO, TCSANOW, &oldt);
  fcntl(STDIN_FILENO, F_SETFL, oldf);


  if(ch != EOF)
  {
    ungetc(ch, stdin);
    return 1;
  }


  return 0;
}
#endif // GETCH_H_INCLUDED
 

int main(int argc, char *argv[])
{
    while (!kbhit())
    {
        wait++;
    }
    if (ch==' ') printf ("you typed space \n");
    if (ch=='\n') printf ("you typed enter\n");
  
 while (!kbhit())
    {
        wait++;
    }
    if (ch==' ') printf ("you typed space \n");
    if (ch=='\n') printf ("you typed enter\n");
 
  
}
