Two tools to deal with Diskimages

[bluecard]

This is my first post in this forum.
I start to write 2 tools,one of them to create empty diskimage in any size
kb,Mb,even Gb and second tool read/write data to diskimage from source/target file.

using DevC++ as IDE ,Console project

download here
mud_img.exe
mud_rw.exe

First of all, hello.
Next, some issues:

1. Nobody with common sense will download a program without source code. Especially from someone with no prior reputation.
2. Not everyone on this forum uses w1nbl0ws. All the more reason to distribute source.
3. What exactly are the advantages between your software, as opposed to say FDisk?
- One can write directly to a flat disk with some hex-editor. Does your software support a multitude of filesystems?
- Failing that, someone can just mount the disk in their host OS and edit the files inside.
4. Not exactly the best sub forum to post this in.

second after all
from 0 to N
try to step in programming,
my small program is alfa version ,i wll put code here:

Code: Select all

#include <stdio.h>
#include <fcntl.h>
#include <windows.h>
#define DEBUG(x)    {printf("\n[DBG]%s",x);}
#define MAX_ARG     5

#define F_KILO      1
#define F_MEGA      1024
#define F_GIGA      1024*F_MEGA

if (argc ==1)
{ help_info();
return 0;
}

if (argv[1][0]=='-' && argv[1][1]=='f' )

Just wanted to give you my thanks for the read image source code.

Any chance for the write image source ?

If not, no worries. Just wanted to say thank you.

Kortath: The above source code is of low quality and isn't portable, which the tool easily could have been. It's also a really simple program that an experienced C programmer could write in a couple of minutes. I'm not sure what this program does what a simple Unix dd(1) call couldn't do.

Wasn't the point of my reply. I would like to see how HE writes external bin files to the img file. Yes, dd can do it. But I would like to see how he does it.
