PR_GETZONEID(3PROC) Process Control Library Functions PR_GETZONEID(3PROC)

NAME


pr_getzoneid - inject getzoneid system call into victim process

SYNOPSIS


Process Control Library (libproc, -lproc)
#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.

INTERFACE STABILITY


Uncommitted

MT-LEVEL
See LOCKING in libproc(3LIB).
