32.Sh DESCRIPTION
33The
34.Fn proc_get_priv
35function is a convenient way to read the /proc privilege file for the
36process
37.Fa pid .
38The
39.Fn proc_get_priv
40function takes care of allocating memory for the privilege set and
41ensures that it is large enough to hold all of the privilege sets.
42The definition of the
43.Sy prpriv_t
44structure may be found in
45.Xr proc 4 .
46.Pp
47The
48.Fn proc_free_priv
49function releases the memory that was allocated by a call to
50.Fn proc_get_priv .
51It is safe to pass the
52.Dv NULL
53pointer in as
54.Fa prp ,
55the function will simply return without taking any action in that case.
56.Sh RETURN VALUES
57Upon successful completion, the
58.Fn proc_get_priv
59function returns a pointer to an allocated
60.Sy prpriv_t
61with the privileges of
62.Fa pid .
63Otherwise,
64.Dv NULL
65is returned to indicate an error occurred.
