27.Sh DESCRIPTION
28The
29.Fn pr_getzoneid
30function injects the
31.Xr getzoneid 3C

35If the process handle
36.Fa P
37is the value
38.Dv NULL
39then this will be equivalent to calling
40.Xr getzoneid 3C
41on the currently running process.
42.Pp
43The
44.Fn pr_getzoneid
45function only works on active processes.
46Process handles that correspond to core files, zombie processes, or ELF objects
47do not support system call injection.
48.Sh RETURN VALUES

50.Fn pr_getzoneid
51function's return value is that described in
52.Xr getzoneid 3C .
53Otherwise,

55is returned and
56.Sy errno

58.Er ENOSYS
59to indicate that the system call could not be injected.
