I'm not familiar with the conio.h header file. However, I did a quick search on it. It seems to define a lot of screen-based functions. You may want to look into the curses library on UNIX systems (libcurses.a or libncurses.a). They provide similar functionality. Go to a search engine like "google.com" and do a search on "Curses Library Functions" or something similar to that.

scr_dump
curs_scr_dump(3) Library Functions Manual curs_scr_dump(3)
NAME
curs_scr_dump, scr_dump, scr_init, scr_restore, scr_set - Read or write a Curses screen from or to a file
SYNOPSIS
#include <curses.h>
int scr_dump(
const char *filename ); int scr_init(
const char *filename ); int scr_restore(
const char *filename ); int scr_set(
const char *filename );
LIBRARY
Curses Library (libcurses)
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
scr_dump, scr_init, scr_restore, scr_set: XCURSES4.2
Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The scr_dump routine writes the current contents of the virtual screen to filename.
The scr_restore routine sets the virtual screen to the contents of filename, which must have been written using scr_dump. The next call to
doupdate restores the screen to the way it looked in the dump file.
The scr_init routine reads the content of filename and uses it to initialize the Curses data structures that describe what the terminal
currently has on its screen. If Curses determines that the data is valid, it bases its next update of the screen on this data rather than
clearing the screen and starting from scratch. Applications call scr_init after an initscr or a system call (see system(3)) to share the
screen with another process that executed scr_dump after endwin. Curses declares the data invalid if the time stamp of the tty is old or
the terminfo capabilities rmcup and nrrmc exist.
The scr_set routine is a combination of scr_restore and scr_init. This routine tells the program that the information in filename is what
is currently on the screen and is what the program wants on the screen. The scr_set routine can be thought of as a screen-inheritance
function.
To read or write a window from or to a file, use the getwin and putwin routines (see curs_util(3)).
NOTES
The header file <curses.h> automatically includes the header file <stdio.h>.
RETURN VALUES
All routines return the integer ERR upon failure and OK upon success.
