Good evening,

Thanks for this.

I took a look at user_access() but wasn't sure that it would do what I needed.  I have to admit to being a newbie as far as Drupal development goes.  I normally work on cor accessibility.

As far as user_access() I see that it can accept a user object, but that it also needs me to pass a permission to check.  What permission would I be checking to see if the current system path can be accessed?  This is why menu_get_item() seemed more appropriate.  It would be nice if there was a function like menu_get_item() that accepted the user object like user_access() does.  Perhaps I'll ad an issue as a feature request for d8 if this doesn't already exist in some hidden corner of d6.

That is, regardless who the current user is, I would like to see if there is a function to let me know if user0 can access the current page, essentially a test to see if the current page is available to anonymous users or not.
>>>>>> I don't think there's an easy way. The access checking for menu_get_item() is done in _menu_check_access(). This figures out and calls the access callback for the particular menu item. For the most general case of a menu item with a custom access callback, it would probably not be possible to modify the function to check a specific $account instead of the current global $user, without some sort of hack.
