Hi, Is there a tool to produce a dependency graph for C headers ?If that matters (i.e. someone has already studied it), i am interested in the header situation in the FreeBSD kernel. It may be a well known thing, but i just realized that <sys/systm.h> is entagled with <sys/libkern.h> and both bring in a lot of other headers, and you cannot bring in simply the string.h functions, or printf, because there is no leaf header for them. I don't know if this is the only case, or there are other 'classes' which are intermixed with lots of other stuff. I suppose the problem has been already discussed and it is just the result of historical reasons, but is there any reason other than ENOTIME why (to cite things that are trivial to fix while preserving compatibility): - we don't have sys/string.h with all the memcpy/bcopy and friends that are currently spread between systm.h and libkern.h - printf/scanf and strto*() are not in their own header; and so on ? cheers luigi
Not sure if it's been done before, but it sounds like a good job for Perl or (I can't believe I'm suggesting this) Ruby. -Garrett _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
