Copy/Read/Write a binary file(.mp3)
Hi all,
The job is to read a .mp3 binary file and create(write) a new .mp3 file which is same as the original file. So, the basic thing we will be trying to do is to read/write of binary file(.doc, .pdf, .xls, .mp3). So the code should finally create a binary file(say a .mp3), which when opened with a player, should be recognized and played correctly.
Has anyone worked on this?
I mean, it will be appreciating if they can help me in getting started with this.

Re: Copy/Read/Write a binary file(.mp3)
THought it would be useful for someone, so heres the code


#include <iostream>
#include <fstream>
using namespace std;

int main () {
  filebuf *pbuf;
  ifstream sourcestr;
  ofstream desstr;
  long size;
  char * buffer;

  sourcestr.open("C:\\E_Drive\\Projects\\I-Radio\\Jashnebahaara.mp3",ios::in | ios::binary);
  desstr.open("C:\\E_Drive\\Projects\\I-Radio\\Jashnebahaara1.mp3", ios::out | ios::binary);
    // get pointer to associated buffer object

  // get file size using buffer's members
  size=pbuf->pubseekoff (0,ios::end,ios::in);
  pbuf->pubseekpos (0,ios::in);

  // allocate memory to contain file data
  buffer=new char[size];

  // get file data 
  pbuf->sgetn (buffer,size);


  // write content to Jashnebahaara1.mp3


  return 0;
