pr_setitimer
—
inject setitimer system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_setitimer
(struct ps_prochandle
*P, int which, const struct
itimerval *itv, struct interval *oitv);
The
pr_setitimer
()
function injects the setitimer(2)
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
setitimer(2) on the currently
running process.
The arguments which, itv, and oitv have the same meaning as in setitimer(2). See setitimer(2) for the full description and purpose of the setitimer system call and its arguments.
The
pr_setitimer
()
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_setitimer
() function's return value is that
described in setitimer(2).
Otherwise, -1 is
returned and
errno is
set to ENOSYS
to indicate that the system call could
not be injected.
For the full list of errors see the ERRORS section in setitimer(2).
The pr_setitimer
() function will fail
if:
ENOSYS
See LOCKING in libproc(3LIB).
