using fstream is there a way to tell the file size of a file you open for readonly access?  I'd like this to be a 100% ANSI C++ compliant code.

Other question is what if the size of the file is greater than what the maximum unsigned int can hold.  For instance say you have a file size that is 2^33 bytes.  I doubt there 100% ANSI C++ compliant code for this but just and extra question.

I've tried using fstream::tellg and fstream::setg to figure out the file size but to no avail.
