Hi.  Is it possible to get the filename of a file that has been opened with fopen?  In other words, I have a global FILE pointer.  It gets opened in main().  Later, I want to be able to get the filename associated with it.  Can I use the file pointer to get it, or do I need to save the filename in memory?

Thanks.

unfortunately not.... I've hacked the include files on linux and the filename is not included anywhere. Why can't you just globally store the filename when you globally store the file?

I can, but didn't want to do that if it wasn't necessary. The program is hefty to begin with and keeping memory allocation to a minimum is desirable.  Thanks for your info.

I'm trying to remove the TOP portion of the file.  So I'm reading the bottom portion of the file, saving it to a buffer, removing the original file (with unlink -- which is where the filename comes in) and writing the buffer out to a new file with the same file name.  Can you think of a more efficient way of doing it?
