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