Description Red Hat Bugzilla 1999-05-12 00:02:46 UTC 
The openmode element ios::ate of the Standard C++ I/O
library does not work. When a file has been opened, the file
position pointer is still at the beginning. This breaks any
C++ program that use ios::ate upon opening a file to seek to
the end of the file immediately, without doing an explicit
seekg(0,ios::end). In RHL 5.2 it works fine.

#include <iostream.h>
#include <fstream.h>

int main(int, char*[])
{
    ifstream
inFile("PUT_YOUR_FILENAME_HERE",ios::in|ios::binary|ios::nocreate|ios::ate);
    cout << "filesize is " << inFile.tellg()
        << ", but should be ";
    inFile.seekg(0,ios::end);
    cout << inFile.tellg() << endl;
    exit(0);
}
