PR_RENAME(3PROC) Process Control Library Functions PR_RENAME(3PROC)
NAME
pr_rename - inject rename system call into victim process
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> int pr_rename(
struct ps_prochandle *P,
const char *old,
const char *new);
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
For the full list of errors see the
ERRORS section in
rename(2).
The
pr_rename() function will fail if:
ENOSYS An error occurred while trying to invoke the agent LWP
and inject a system call in the process handle
P or the
process handle
P does not support system call injection.
