PR_RENAME(3PROC) Process Control Library Functions PR_RENAME(3PROC)

NAME


pr_rename - inject rename system call into victim process

SYNOPSIS


Process Control Library (libproc, -lproc)
#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.

INTERFACE STABILITY


Uncommitted

MT-LEVEL
