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