Darwin-xnu: The Darwin Kernel

Interesting side note, source contains 8701 goto statements -- I like it.

     $ find . -name "*.c" -exec grep goto {} \; -print | wc -l
     8701

Most of it to unify releasing resources on function returns to one place at the end of the function body. This is what makes RAII in C++ so important/convenient.

You are saying it like if 'goto' was a bad thing. This is pretty normal for any kernel/system projects.

And the same command on the Linux source returns 160,818.

It's interesting how Dijkstra's take on the use of goto has blinded a large number of developers on the practicalities of its use.

This reminds me of the C++ developer who, when asked what his favorite snippet of C++ source code was, replied with:
