setvbuf not able to make stdin unbuffered

Question

My main intention was to make getchar return as soon as it gets a character instead of waiting for the ENTER key. I tried this

int ma

In case you are trying this under Linux or another Unix-like system, it is the terminal that buffers the input and only passes an entire line. You can use ncurses to circumvent this:

#include 

int main()
{
    initscr();
    getch();
    endwin();

    return 0;
}

Compile with:

gcc -o main main.c -lncurses
