No, conio's getch is DOS-specific; it uses a certain system call which always works by single characters. To write more portable code, which uses standard functions, you need to call the tcsetattr function with the ICANON bit reset in the c_lflag member of its last argument (which is a structure). After that, any input function that you call will return after a single character has been read from the terminal.
