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.

INTERFACE STABILITY

Uncommitted

MT-LEVEL
