The iostream stuff just seems safer, anyway ...

It is defined in stdio.h. see http://msdn.microsoft.com/library/en-us/vccore98/HTML/_crt_fgetc.2c_.fgetwc.2c_._fgetchar.2c_._fgetwchar.asp?frame=true for an example of using fopen() to obtain a pointer to the FILE info. I dont know much more about it though... good luck! Jason 2006-06-15T04:53:08Z FILE * from std::ofstream?

I need to interface a library that expects to communicate through a FILE * to my code written using ofstream. In these endeavors, I would like to just have my ofstream return a FILE * that this library can use, but I don't see how I can do that. The ofstream.rdbuf() returns a basic_filebuf, but there seems to be no way of getting a FILE * from it in a cross platform way (this code has to work on Mac OSX, using gcc, as well as Windows, using the MSVC.NET compiler). Am I doomed to a C-style interface to my lower level file objects, just because this library expects a FILE *? I'm sure i'm not the only one who has run into this ...
