'Porting' conio.h written code to curses.h
When porting code written using conio.h
to use curses.h
, you'll need to make several changes to adapt to the different functions and capabilities provided by the curses
library. Here are some key considerations and changes to make:
Include the
curses.h
header at the beginning of your code:c#include <curses.h>
Initialize the
curses
library by callinginitscr()
at the beginning of your program:cinitscr();
Replace
clrscr()
withclear()
to clear the screen:cclear();
Instead of using
getch()
to read a character from the keyboard, usegetch()
orwgetch()
from thecurses
library:cint ch = getch(); // or wgetch(stdscr);
Replace
kbhit()
withnodelay()
to check if a key is pressed:cnodelay(stdscr, TRUE);
int ch = getch();
if (ch != ERR) {
// A key was pressed
}
Use
printw()
ormvprintw()
to display text on the screen:cprintw("Hello, world!");
mvprintw(y, x, "Text at coordinates (x, y)");
Replace
textcolor()
andtextbackground()
withattron()
andattroff()
to set text attributes:cattron(A_BOLD); // Set bold attribute
attron(A_UNDERLINE); // Set underline attribute
// ...
attroff(A_BOLD); // Turn off bold attribute
attroff(A_UNDERLINE); // Turn off underline attribute
Use
move()
ormvprintw()
to set the cursor position:cmove(y, x);
mvprintw(y, x, "Text at coordinates (x, y)");
After you're finished using
curses
, callendwin()
to clean up and restore the terminal settings:cendwin();
These are some of the basic changes you'll need to make when porting code from conio.h
to curses.h
. Depending on the specific functions and features used in your code, there may be additional adjustments required. The curses
library provides extensive capabilities for text-based user interfaces, and the documentation for curses
will provide more details on how to use specific functions.
