Page owned by user

[potterv]

Hello people,

I want of find the number of pages each user has in FreeBSD kernel.
Can anyone help me with this? I know there is no direct link between user and pages but between pages and object. But I am having trouble connecting that to find the user that owns that page.
Help!!

Are you talking about virtual memory or something else?

...the user that owns that page.

The process owns the page.

However, if you look at /usr/include/sys/proc.h there is a member in struct proc

struct proc {
    ...
    struct ucred *p_ucred; /* (c) Process owner's identity. */
    ...
}

which you can use to extract the data you need.
