You have to find a different way.  Normally, you keep track of the name as a character string separate from the FILE pointer.

Hi Carl3003,

You would have specified the file name somewhere when you obtained the FILE * fp. You will have to use that. There is no ANSI C function which will give you the file name when you supply the FILE *.

There are some other platform specific solutions such as examining ls -l /proc/<pid>/fd on various flavours of linux. However, I will still recommend using the information yuo already have rather than fish for it in an unportable way.

cheers
