pr_exit — inject
exit system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_exit(struct ps_prochandle *P,
int status);
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.
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.
For the full list of errors see the ERRORS section in exit(2).
The pr_exit() function will fail if:
ENOSYSSee LOCKING in libproc(3LIB).
