FIX: ifstream Object Loses Character in Text Mode (102158)

MORE INFORMATION

The following code example demonstrates this problem by filling a buffer with the character sequence "01234567890..." and using an ifstream object to copy the data to another buffer. The transferred sequence reads as "013456..." Only the character "2" is missing from the sequence. The remainder of the sequence transfers correctly.

Sample Code

/*
 * Compiler options needed:  -GX for 5.0 only
 */ 

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

// To resolve the problem using Visual C++ 5.0, use the
// following three statements instead of the preceding two:
// 
// #include <iostream>
// #include <fstream>
// using namespace std;


void main(void)
{
   ofstream os("test.tmp");
   for (int i = 0; i < 512; i++)
   {
      os.put((char)('0' + i % 10));
   }
   os.put('\n');
   os.close();

   streampos pos;
   ifstream is("test.tmp");
// To resolve this error using Visual C++ 4.x and earlier, use the
// following line to open the ifstream instead of the line above.
// ifstream is("test.tmp", ios::binary);
   for (int k = 0; k < 10; k++)
   {
      pos = is.tellg();
      cout << (char)is.get();
   }
}
