PR_GETZONEID(3PROC) Process Control Library Functions PR_GETZONEID(3PROC)
NAME
pr_getzoneid - inject getzoneid system call into victim process
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> zoneid_t pr_getzoneid(
struct ps_prochandle *P);
DESCRIPTION
The
pr_getzoneid() function injects the
getzoneid(3C) system call into the
target process
P by means of the agent LWP. If the process handle
P is the
value NULL then this will be equivalent to calling
getzoneid(3C) on the
currently running process.
The
pr_getzoneid() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects do
not support system call injection.
RETURN VALUES
Upon successful completion, the
pr_getzoneid() function's return value is
that described in
getzoneid(3C). Otherwise,
-1 is returned and
errno is
set to ENOSYS to indicate that the system call could not be injected.
ERRORS
For the full list of errors see the
ERRORS section in
getzoneid(3C).
The
pr_getzoneid() function will fail if:
ENOSYS An error occurred while trying to invoke the agent LWP
and inject a system call in the process handle
P or the
process handle
P does not support system call injection.
