In my opinion, it's just crazy. Okay, you've convinced me. In this case, anyway, it makes sense to add the structure declarations to the header file. That's a lot less objectionable than adding a new include line (even though the compiler doesn't care). By the way, if anyone cares, this discussion reminded me something interesting. It's sort of the opposite side of the coin, a case where a source file would do something _different_ each time it was included. The program itself was a fairly simple thing to calculate and print prime numbers. The interesting part was that this didn't happen when you would _run_ the program -- it happened when you _compiled_ the program! Lots of preprocessor stuff to make it work. And the only way to persuade the compiler to go into a loop was for the source file to include itself. :-) Alan Stern -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
