It would be great if a clone of that tool could be made available covering all the OSS parts of Mac OS X. We are aware of the lack of source search at opensource.apple.com. We recently redesigned the site to eliminate the ADC logins, which should help improve the coverage in Google's index. So, for now, use Google with a site: query. If you want a way to get all of the source for a release in order to grep locally, there is a recipe using darwinbuild here: This email sent to site_archiver(a)lists.apple.com

In an IDE I had (CodeWarrior?) one could even step through the library functions in the debugger, and if the sources were not available, at least seeing the ASM. Very good for learning.

In general, we consider the Mach stuff to be implementation detail, and want you to use franewrks so we can feel free to change the implementation details, in particular, the interface contracts, any time we want. I also have the Mach 3 standard. But I found it convenient checking man pages.

Not sure if it always works, but adding site:opensource.apple.com to a Google search has worked for me recently. I know it didn't used to work.

Guys try to be nice with the server :), anyway the site doesn't link to third-parts code, one last comment I am using only Robert reference to have a "picture" of previous versions and I have the current versions on a local disk, for instance, my svn working copy of FreeBSD source ~= 300 MB (not strictly the kernel part), so it's not a big deal to host source.
