    cls in C

    um how do I do a csls in C I might have asked this be4 but in that case I cant remember the answer and I cant find the topic anyway....
    They say that if you play a Windows Install CD backwords, you hear satanic messages. That's nothing; play it forward and it installs Windows.

    system("cls");
    Read the FAQ.

    Clearing the screen
    The world is waiting. I must leave you now.

    cls only works in DOS-WIN, in unix is clear. maybe try something like this

    Code:
    #ifdef UNIX
      #define CLS "clear"
    #else
      #define CLS "cls"
    #endif
    Then you just call, system(CLS);

    if you're using linux, you can use system("clear"); or use curses to make the job, example:
    Code:
    #include <curses.h> 
    
    void clrscr(void)
    {
        static int init;
    
        if (init == 0)
        {
            initscr();
            init = 1;
        }
    
        clear();
        refresh();
    }

    Or just convert this function from Pascal to C:

    Code:
    procedure Cls(Color : byte); assembler;
    asm
     mov    AX, $A000    { move the video segment into AX cause }
     mov    ES, AX       { you can't load a segment reg directly }
     mov    AL, [Color]  
     mov    AH, AL       { REG / REG is faster than MEM /REG }
     mov    CX, 32000    { 64k / 2 since we're using word values }
     xor    DI, DI       { fast way of saying DI = 0 }
     rep    STOSW        { mov ES:[DI], AL; dec CX, jcxz done }
    end;
    It'll clear the screen filling it with a color.
