pr_getitimer
—
inject getitimer system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_getitimer
(struct ps_prochandle
*P, int which, struct itimerval
*itv);
The
pr_getitimer
()
function injects the getitimer(2)
system call into the target process P by means of the
agent LWP. If the process handle P is
NULL
then this will be equivalent to calling
getitimer(2) on the currently
running process.
The arguments which and itv have the same meaning as in getitimer(2). See getitimer(2) for the full description and purpose of the getitimer system call and its arguments.
The
pr_getitimer
()
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_getitimer
() function's return value is that
described in getitimer(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 getitimer(2).
The pr_getitimer
() function will fail
if:
ENOSYS
See LOCKING in libproc(3LIB).
