PR_CREAT(3PROC) Process Control Library Functions PR_CREAT(3PROC)
NAME
pr_exit - inject exit system call into victim process
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> int pr_exit(
struct ps_prochandle *P,
int status);
DESCRIPTION
The
pr_exit() function injects the
exit(2) system 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
exit(2) on the currently running
process.
The argument
status has the same meaning as in
exit(2). See
exit(2) for the full description and purpose of the
exit system call and its
arguments.
The
pr_exit() 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_exit() function's return value is
that described in
exit(2). Otherwise,
-1 is returned and
errno is set
to ENOSYS to indicate that the system call could not be injected.
If the
pr_exit() function is called with the value of
P set to NULL,
then the function will not return.
ERRORS
For the full list of errors see the
ERRORS section in
exit(2).
The
pr_exit() 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.
