PR_CREAT(3PROC) Process Control Library Functions PR_CREAT(3PROC)
NAME
pr_creat - inject creat system call into victim process
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> int pr_creat(
struct ps_prochandle *P,
const char *filename,
mode_t mode);
DESCRIPTION
The
pr_creat() function injects the
creat(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
creat(2) on the currently running process.
The arguments
filename and
mode have the same meaning as in
creat(2). See
creat(2) for the full description and purpose of the
creat system call and
its arguments.
The
pr_creat() 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_creat() function's return value is that
described in
creat(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
creat(2).
The
pr_creat() 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.
