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