pr_llseek — inject
llseek system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_llseek(struct ps_prochandle
*P, int filedes, offset_t
offset, int whence);
The
pr_llseek()
function injects the llseek(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
llseek(2) on the currently running
process.
The arguments filedes, offset, and whence have the same meaning as in llseek(2). See llseek(2) for the full description and purpose of the llseek system call and its arguments.
The
pr_llseek()
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_llseek() function's return value is that
described in llseek(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 llseek(2).
The pr_llseek() function will fail if:
ENOSYSSee LOCKING in libproc(3LIB).
