Hmm, in the example above, -r is not needed because I specified a list of files.
$ grep cb_log src/pacman/*.c

-r is needed when running on directories (just like rm) :
$ grep -r cb_log .

But sometimes you get unwanted spam, so it is better to only search
the .c files like above.
Another way :
$ find . -name "*.c" | xargs grep logcb

Finally, a more powerful tool is cscope :
But I didn't manage to get used to this tool yet, I tried it once or
twice then I always forget about it :P
