fstream.getLine() does an abort at newline

[shyam]

Hi All

I want to know if there is any problem with using
fstream.getLine(char*, int ) function.

My problem is that when I read a file using it, the program aborts when
it reads the terminating newline of a file.

This happens if I set the exception bits using
exceptions(fstream::badbit | fstream::failbit | fstream::eofbit ).
Otherwise it does not happen.

Is there any alternative??

thanks in advance

You can use getline from <string>:

#include <string>
istream& getline( istream& is, string& s, char delimiter = '\n' );

The function is called 'getline'. Case matters in C++.

Do you catch those exceptions?

Why aren't you using std::getline with std::string instead?

The problem is at the end of file

Since I am setting the bits for eofbit so at EOF the function throws
failure exception
