pr_waitid — inject
waitid system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_waitid(struct ps_prochandle
*P, idtype_t idtype, id_t
id, siginfo_t *infop, int
options);
The
pr_waitid()
function injects the waitid(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
waitid(2) on the currently running
process.
The arguments idtype, id, infop, and options have the same meaning as in waitid(2). See waitid(2) for the full description and purpose of the waitid system call and its arguments.
The
pr_waitid()
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_waitid() function's return value is that
described in waitid(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 waitid(2).
The pr_waitid() function will fail if:
ENOSYSSee LOCKING in libproc(3LIB).
