Here are WP Function Reference for all users functions.
But I need list of core functions like:
init, restrict_manage_posts etc.
Here WP Action Reference – list off all core functions, but there are very pure description.
Where can I find it?
Where can I find WordPress core functions list and description?
Unfortunately AFAIK , there is no ONE place with perfect documentation.
Some of the more known places are :
The codex .
http://adambrown.info/p/wp_hooks/hook/init
http://hitchhackerguide.com/function-filter-action-index/
http://wpseek.com/
http://queryposts.com/
and you can find more on google ..
There is another choice (which might be the best) and that is reading the INLINE comments inside the core file themselves ..
