Moving stream pointer to next line in file

[snipslog]

Is there a way to move the position without reading the line? I want to just read the first char on the line, and if it is not the one i want it moves onto the next line.

if ( (char)fgetc( file ) == ';' )
{
//move to next line
}
else
{
//other code...
}

MyCPlusPlusStdStreamObject.ignore(unsigned(-1), '\n');

By the way, comments are a bit more complex than just that. What if spaces preceed it? ;)

Can you give me a link to msdn? I can't find that function anywhere. Also, in this file format there can only be comments at the beginning anyway.

MSDN link? This is a member function on the std::ifstream object, which is the usual class people use to read from files in C++: http://www.cplusplus.com/reference/iostream/ifstream/

If you want to do it using Windows-Only code, you will just have to keep reading in bytes until you read \n - which is a bit more than just one line of code.

I'm using the fopen_s() function in the CRT library. Is it better to handle files with the standard library?

[LB]

Yes, it is much easier, and the code will work on any platform. Even if you're staying on Windows, the ease of the C++ library is more than worth it.

I just have one more question. When I call ifstream->close() after using the ignore(), does that remove the line from the file or does it just ignore it when it is reading it?

EDIT: Nevermind, it doesn't.

ifstream can only do input operations, meaning it can work with files marked as read only. To output to files use ofstream. ;)
