pr_memcntl —
inject memcntl system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_memcntl(struct ps_prochandle
*P, caddr_t addr, size_t
len, int cmd, caddr_t arg,
int attr, int mask);
The
pr_memcntl()
function injects the memcntl(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
memcntl(2) on the currently running
process.
The arguments addr, len, cmd, arg, attr, and mask have the same meaning as in memcntl(2). See memcntl(2) for the full description and purpose of the memcntl system call and its arguments.
The
pr_memcntl()
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_memcntl() function's return value is that
described in memcntl(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 memcntl(2).
The pr_memcntl() function will fail
if:
ENOSYSSee LOCKING in libproc(3LIB).
