OIOIC is a completely new object-oriented mechanism for the C programming language.
Please download the "OIOIC-Primer-2nd-Edition.tar.gz" (an English version in it.)
http://code.google.com/p/oioic/downloads/list

Welcome your advice!

Using OIOIC, you can describe the flower, birds, grass, insects, trees, houses ...
Using OIOIC, you can describe the elements, atoms, protons, electrons ...
Using OIOIC, you can describe the earth, the sun, the Milky Way galaxy, collapsar ...
Using OIOIC, you can describe ...

1. OIOIC perfectly supplies the gap of object-oriented technology for the C programming language;
2. OIOIC perfectly solved the multiple inheritance problem in the Software World;
3. OIOIC perfectly objectivizes multithreading access control of object;
4. OIOIC unifies the norm of components in the Software World;
5. OIOIC unifies the structure of code tree in the Software World;
6. OIOIC unifies the thinking of object-oriented programming in the Software World;
7. OIOIC unifies all advanced programming languages in the Software World, to make the C programming language as the preferred.

I voted to remove your message yesterday, and I'm voting again today.

And apparently you're spamming other message boards.

If this is an advert for a commercial product, you should be paying codeproject properly to put it in front of out eyes.
If it is a project you've created, and want other people to know about, how about writing an article about it? Show us a useful application. Show us a real world problem this solved.

We're used to alphabet soup of multiletter acronyms, but they're usually only 3 letters long.

As for "...you can describe the flower, birds, grass, insects, trees, houses...", it sounds like Poetry SDK to me, and we've had that for 1000's of years.

If this is your result of years of hard work, I congratulate you, but spamming our message boards is not the way to make friends and influence people.

I wish you luck in the correct venue(s),

Iain.

Hi,
I am using QNX IDE.
I need to create a file which is exactly 2112 bytes.T.he data written to the file must be of type char(in Hexadecimal format.
I am trying following code.

#include "stdio.h"
#include "conio.h"
#include<stdlib.h>
#include<fstream.h>
void main()
{
FILE* fs;
fs=fopen("c:\\RajC\\randomF.txt","w");
srand(255);
for(unsigned char i=0;i<255;i++)
{
printf("%c\t",rand());
fprintf(fs,"%x\t",rand());
}
getch();
}
but the output of the above program gives me a file of 6.08KB,whereas I need just a filesize of 2112bytes. 
I need to use this file for testing on a hardware.
   */

Can anyone help me.
Thanks in advance.

Writing a single char takes 1 byte. including '\t' tabs. You are running the loop 255 times. So if you just print 1 char in the loop, the file size becomes 255 bytes. if you print the hex value, it defers based on the number it generates. May be you can format the string to a standard size and calculate the size accordingly. Remember the tab takes 1 byte.

If you are able to call Windows APIs, you can use SetFilePointer followed by SetEndOfFile.

This should work:

#include <io.h>
#include <fcntl.h>

void main()
{
   int fd=open(file-path,O_RDWR|O_BINARY|O_CREAT|O_TRUNC);
   if (fd != -1)
   {
      const size_t numBytes = 2112;
      unsigned char buffer[numBytes]={0};
      const int x = write(fd, buffer, numBytes);
      close(fd);
   }
}

Thanks a lot for the reply.
But can u gimme a C++ style solution,i.e. using fstream.
I am trying it this way:

void Create_Page_File()
{
	    int iCount;
	char wbuf[PAGESIZE];//,FBuff[PAGESIZE];
	int rand_no;
	/* Initialise buffer before use */
	memset (wbuf, 0, PAGESIZE);
	ifstream infile("/tmp/TestData.bin");
	ofstream outfile("/tmp/TestData.bin");
     
 	for( iCount = 0; iCount < PAGESIZE; iCount++ )
	{
		 //Prepare random data 
			rand_no = rand( );
		    wbuf[ iCount ] = ( rand_no % 0xff );	
		//}
		outfile.write( &( wbuf[ iCount ]), 1 );
		cout<< wbuf[iCount]<<" ";
    }

}

But the resulting file I am getting is in character format,nd not hexadecimal.
Please Help me.
Thanks and regards,

It creates a file called b.b in the current directory which is exactly 2112 bytes in length. Want a different filename? Then change it in the constructor. Want a different file length? Then change the length (2112 in this case) in the string constructor

Otherwise, what do you mean by 'not working'?
