Simple input and output

Output

The routines that low-level ETI provides for writing to stdscr are similar to those provided by the Intro(3S) library for writing to a file. They let you

write a character at a time -- addch
write a string -- addstr
format a string from a variety of input arguments -- printw
move a cursor or move a cursor and print character(s) -- move, mvaddch, mvaddstr, mvprintw
clear a screen or a part of it -- clear, erase, clrtoeol, clrtobot

Following are descriptions and examples of these routines.

CAUTION: The ETI library provides its own set of output and input functions. You should not use other I/O routines or system calls, like fprintf(3S) and fscanf(3S), in an ETI program. They may cause undesirable results when you run the program.
