    Talking asm

    ammm
    in c you can call asm...
    i cannot go into detail about this,


    you can take a look at this code fragment



    void setcur(int _setcursor_){
    union REGS reg;
    reg.h.ah = 1;


    if( _setcursor_ > 2 ){ _setcursor_=_setcursor_ % 2 ;}
    if( _setcursor_ == 0 ) { reg.h.ch = 32;}
    if( _setcursor_ == 1 ) { reg.h.ch = 1;}
    if( _setcursor_ == 2) { reg.h.ch = 8;}
    reg.h.cl = 9;
    int86(0x10,&reg,&reg);
    }


    this function i made, will set the cursor to normal, Block or set the cursor off

    as you can see this is some assembly. if i am not mistaken....


    well to every one you can copy the code freely


    thx...
