Back in the good old days, when programming
in DOS using the Borland compiler, I could
use the functions getch and getche for 
non-buffered and no echo keyboard input.
I'm writting a C GNU Linux program and there
isn't any getch or getche functions available.
 getchar isn't any good and neither is getc
because they both use buffered input and
need the user to press the ENTER key before
accepting the input. 
I need a keyboard input function that will take
in one character immediately, without the
user having to press ENTER afterwards.
Is there such a function in C GNU Linux ?
If not, is there any other way to accomplish
this simple task with C GNU Linux?
( I hope its easy. I'm no expert )

Amazing what you can find in a good WROX book!

 #include <termios.h> 
char ky = 'X'; 
struct termios original_t, new_t; 
tcgetattr(fileno(stdin), &original_t); 
new_t = original_t; 
/* got the next line from POSIX */ 
/* turn off CONICAL input and echo */ 
new_t.c_lflag &= ~(ICANON | ECHO); 
printf("\n\t Enter a character > "); 
/* set new attributes */ 
tcsetattr(fileno(stdin), TCSAFLUSH, &new_t); 
fflush(stdin); 
ky = getchar(); 
/* Return to normal */ 
tcsetattr(fileno(stdin), TCSANOW, &original_t);
