Receive character in C

How do I do a function in C equal to the function Readkey of Pascal or equal to the function Lastkey of the old man Clipper? I want to receive only one character separately for each key pressed. Create menus, receive key ESC, etc. Thanks in advance.

    Pascal’s Readkey equivalent is Clipper’s Inkey, not Lastkey. Which of the two behaviors do you want?

In C you need an external library to do this. The default language does not define a way to do this. An external library that displays this feature is ncurses; there must be others, but I don’t know them.

Example taken from NCURSES Programming HOWTO and with some changes to my taste:

#include <ncurses.h>

int main(void) {    
    initscr();                /* Start curses mode              */
    printw("Hello, World!");  /* Print Hello. World!            */
    refresh();                /* Print it on to the real screen */
    getch();                  /* Wait for user input            */
    endwin();                 /* End curses mode                */
    return 0;
}
