g++ compilation error

-----------------------------------

Hey guys,

I'm quite confused here. My program works perfectly when compiled on Visual Studio 2008 but it doesn't compile on G++.

I don't even understand the error. I know that the ifstream is part of the C++ standard library so it makes even less sense:


isbnprefix.cpp: In function 'int registered(FILE*, int)':
isbnprefix.cpp:32: error: no matching function for call to 'std::basic_ifstream::basic_ifstream(FILE*&)'
/usr/include/c++/4.1.2/fstream:442: note: candidates are: std::basic_ifstream::basic_ifstream(const char*, std::_Ios_Openmode) 

My isbnprefix.cpp as follows:
