created file is deleted still program not reporting error

[npchoubey]

See below the simple program
it opens a file for writing
writes one line at time for 199 times and then comes out.
it also checks before every write, whether file is bad or fail.

Problem : What should happen if someone removes the data file ( i.e. "example.txt" ) using ome command, while this program is running.

I have noticed that it keeps running ( on Linux and Solaris ) and does not report either bad() or fail().

This behaviour somewhat looks obivous. My questions are
1) whether C++ provides any , platform independent , functionallity to handle this case? ( I am looking for some api/function not workarounds like close and open file after every operation )
2) Is there anyway to I use fstat() , for fstream ojbect ?

////////////////////////////////////////////////////////////////////
#include <iostream>
#include <fstream>
//#include <unistd.h>
using namespace std;

int main () {
ofstream myfile;
myfile.open ("example.txt");
int i=0;
for( ;; )
{
//sleep(1);
//for loop for delay
for( int ii=0; ii<10000; ii++)
for( int jj=0;jj<10000; jj++);
myfile <<i++<< " Writing this to a file.\n";
myfile.flush();
if( myfile.bad() )
{
cout<<" its bad now "<<i<<endl;
}
else
{
cout<<" not bad "<<i<<endl;
}
if( myfile.fail() )
{
cout<<" its failed now "<<i<<endl;
}
else
{
cout<<" not failed "<<i<<endl;
}

if( i == 199) break;

}
myfile.close();
return 0;
}

Everyony,
I have posted following problem, and would request ur attention to the same.

Firstly please don't create extra threads about the same problem, you can always post to the original thread to bump it to the top of the stack.

1. Not particularly, I would kind have expected the OS to prevent deletion of a file opened for writing.

2. fstat does appear to be a member of ofstream or fstream in my reference.

[npchoubey]

1. OS does not support the NON-deletion of file open for writing.

2. Can , anyone, please tell which reference to look to get details for fstat ( under fstream ). I did looked into http://www.cppreference.com/cppio/index.html , with no luck.

And above all , I shall abide not repeating the same listing with different header

2. Further checking suggests that fstat is a *NIX OS function. As such it is very unlikely to be supported by a standard C++ file class so you will not find it mentioned on line in help pages for standard C++. Your implementation may have an extension that provides this functionality, you will have to look in your implementation documentation to determin this.
