possible solution for clrscr()

[Dinesh Pillay]

People who want to use clrscr and can't seem to get it work with DevC++ for whatever reason can do this

1. Create a clrscr.c file

and add the following code......

#ifndef _CONIO_C_
#define _CONIO_C_

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <windows.h>
#include <string.h>
#include "conio.h"

#ifndef _COLORS_
#define _COLORS_
enum COLORS {
    BLACK,          /* dark colors */
    BLUE,
    GREEN,
    CYAN,
    RED,
    MAGENTA,
    BROWN,
    LIGHTGRAY,
    DARKGRAY,       /* light colors */
    LIGHTBLUE,
    LIGHTGREEN,
    LIGHTCYAN,
    LIGHTRED,
    LIGHTMAGENTA,
    YELLOW,
    WHITE
};
#endif

static int __BACKGROUND = 0;
static int __FOREGROUND = 7;

void
gotoxy(int x, int y)
{
  COORD c;

  c.X = x - 1;
  c.Y = y - 1;
  SetConsoleCursorPosition (GetStdHandle(STD_OUTPUT_HANDLE), c);
}

void
clrscr ()
{
    DWORD written;

    FillConsoleOutputAttribute (GetStdHandle (STD_OUTPUT_HANDLE),
      __FOREGROUND + (__BACKGROUND << 4), 2000, (COORD) {0, 0},
      &written);
      FillConsoleOutputCharacter (GetStdHandle
      (STD_OUTPUT_HANDLE), ' ',
      2000, (COORD) {0, 0}, &written);
    gotoxy (1, 1);
}

#endif

2. store the file in the include folder
3. when u want to use it in an app ... just say
#include <conio.c>

I prefer including stdlib.h and using system("CLS");  (My initals  ;-)  ).  Saves having to include conio.h and conio.c

as i said "possible" solution:) .... man this software is really good .... nice work guys:)

[Dinesh Pillay]

just wanted to add that system("CLS") or system("PAUSE") ... is a little bit slower to respond than and not as smmoth as clrscr() or getche()

.c files should be separately compiled and linked - not included. Only .h files should be included, and these should not contain any data instantiation or function definitions - only (extern) declarations.

This is more efficient from a compiler point of view, (it only compiles the modules that have changed), and if you have more than one module that includes the same .c files containing function code and/or data instantiation, then linker errors will occur.

You may be only writing single module apps at present, so do not see the problem - but such bad practices will bite you in the end.

Question:  What are the Linux/Unix commands equivalent to Windows' CLS and PAUSE commands?  Thanks!

FYI:  I have found CLEAR as the Unix equivalent to Windows' CLS.  But there doesn't seem to be an equivalent to PAUSE as a standard shell command in Unix...
