    What is used instead of dos.h header file

    I have a question I get this error can't include dos.h header.
    I am compiling on a 64 bit computer with a amd processor using window 7 trying to make a 64 bit.exe.

    here's the code, actually I got this from a book and can't get it to run.

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    #include <dos.h>
    
    #define FACE 0x01
    #define LOOP 100
    #define PAUSE 150000
    #define VIDEO 0x10
    #define COLS 80
    #define ROWS 25
    
    void cls(void);
    void locate(int col, int row);
    int rnd(int range);
    void seedrnd(void);
    
    void main();
    {
    	int t,x,y;
    	unsigned long p;
    
    	cls();
    	seedrnd();
    
    	for(t=0;t<LOOP;t++)
    	{
    		x=rnd(80)+1;
    		y=rnd(25)+1;
    		locate(x,y);
    		putchar(FACE);
    	}
    
    	void cls(void)
    	{
    		union REGS regs;
    
    		regs.h.ah=0x06;
    		regs.h.al=0x00;
    		regs.h.bh=0x07;
    		regs.h.ch=0x00;
    		regs.h.cl=0x00;
    		regs.h.dh=ROWS 1;
    		regs.h.dl=COLS 1;
    		int86(VIDEO,&regs,&regs);
    		locate(0,0);
    	}
    
    	void locate(int col, int row)
    	{
    		union REGS regs;
    
    		regs.h.ah=0x02;
    		regs.h.bh=0x00;
    		regs.h.dh=row;
    		regs.h.dl=col;
    		int86(VIDEO, &regs,&regs);
    	}
    
    	int rnd(int range)
    	{
    		int r;
    		r=rand()%range;
    		return(r);
    	}
    
    	void seedrnd(void)
    	{
    		srand((unsigned)time(NULL));
    	}

    I doubt dos.h can be used (or is part of the library that comes) with any modern compilers. That header was designed for use with DOS, an old operating system. Probably Turbo C or another old school compiler will allow it.

    Show us the actual errors and maybe we can help find modern alternatives. This is the problem with legacy platform-specific code: there can be some really cool nuggets of functionality lost to the sands of time due to reliance on old build environments. I am guessing the int86() call is biting you in the bum...

    Here's the error

    Building Dibble.obj.

    Done.
    I'm using pelles c compiler

    I have a bad feeling about this program

    I guessing the code would have to be totally rewritten to implement this program I shouldn't have bought this book but sometimes you can learn things from old books

    Yeah, like history, which can be interesting but may not get you to work on time. Are those nested functions in main()? I don't think this is legal in C anymore.

    I forgot the last } but yeah its in main() oh well do you guys have any suggestions for a modern C book. I could buy.

    	}
    
    	void seedrnd(void)
    	{
    		srand((unsigned)time(NULL));
    	}
    
    
    I didn't copy the code correctly and all the function are suppose to be outside of main() sorry about that sometimes I get in a rush

    Out of pure curiosity what book is this?

    Anyway, there's this book on line:
    The C Book - Table of Contents

    Maybe it is not so good if you are a complete beginner to programming*, or if you could not put up with this:
    The input from so many varied sources has spawned a language a bit like a cross-bred terrier: inelegant in places, but a tenacious brute that the family is fond of. Biologists refer to this phenomenon as ‘hybrid vigour’. They might also draw your attention to the ‘chimera’, an artificial crossbreed of creatures such as a sheep and a goat. If it gives wool and milk, fine, but it might equally well just bleat and stink!

    At the coarsest level, an obvious feature is the multi-file structure of a program. The language permits separate compilation, where the parts of a complete program can be kept in one or more source files and compiled independently of each other.
    Also the "K&R" book seems to have beneficial impact:
    http://en.wikipedia.org/wiki/The_C_P...Language_(book)
    I'm sure that's available cheaply online if not at some library somewhere.

    * in that case maybe go for a "teach yourself C in 30 days" kind of book.
