My teacher’s notes said
“There is a tags file that can be built which will make finding things in the kernel source code easier. You can find source code for a function in the kernel source tree by using “vi -t” and the function name”
Such as:
#vi -t open
can open the source code of open.
But I tried it on my FreeBSD 8.1. It fails…why? How can I configure it?
Thanks!
You need to generate the tags file first with
ctags(1).
