Hi, I'm developing pyalpm at the moment(new codebase, not related to 2005 pyalpm) and I don't really see any example of usage of alpm_option_set_logcb() on pacman.c file there is alpm_option_set_logcb(cb_log); but I can't find where is cb_log declared, so I have no clue about what does that function do(as I haven't neither found where is the actual code of that function, only that is declared on alpm.h)

Why not just using grep or whatever : $ grep -r cb_log src/pacman/*.c src/pacman/callback.c:void cb_log(pmloglevel_t level, char *fmt, va_list args) src/pacman/pacman.c: alpm_option_set_logcb(cb_log); All callbacks (cb) are defined in that callback.c file.

thanks, I didn't know about grep -r

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 : http://cscope.sourceforge.net/ 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

ctags is great as well. ctags -R will build the tag database, and then I could type: vim -t cb_log and it would bring me right to the function without even knowing what file it is in.

Uh yeah, I should definitively have mentioned that, I use ctags all the time. It is probably what I would have used in this case. I would have opened pacman.c in vim, browsing the code, find this line : alpm_option_set_logcb(cb_log); Then I put the cursor and cb_log, press Ctrl+] , and it goes directly to the function. And Ctrl+T to go back. But thanks for the "vim -t" way, I didn't know that one :)
