getch() for GNU/Linux

Code:

#include<termios.h>

#include<unistd.h>

int getch( )

{

struct termios oldt,

newt;

int ch;

tcgetattr( STDIN_FILENO, &oldt );

newt = oldt;

newt.c_lflag &= ~( ICANON | ECHO );

tcsetattr( STDIN_FILENO, TCSANOW, &newt );

ch = getchar();

tcsetattr( STDIN_FILENO, TCSANOW, &oldt );

return ch;

}

You can use this getch() function in C or C++ in Linux, as linux GNU libraries din't provide "Console Input Output <conio.h>". I've Written some functions of ConIO for GNU-C and this is one of that.
