PR_GETSOCKNAME(3PROC) Process Control Library Functions PR_GETSOCKNAME(3PROC)
NAME
pr_getsockname - inject getsockname library call into victim process
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> int pr_getsockname(
struct ps_prochandle *P,
int sock,
struct sockaddr *name,
socklen_t *namelen);
DESCRIPTION
The
pr_getsockname() function injects the
getsockname(3SOCKET) library 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
getsockname(3SOCKET) on the currently running process.
The arguments
sock,
name, and
namelen have the same meaning as in
getsockname(3SOCKET). See
getsockname(3SOCKET) for the full description
and purpose of the
getsockname library call and its arguments.
The
pr_getsockname() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects do
not support library call injection.
RETURN VALUES
Upon successful completion, the
pr_getsockname() function's return value is
that described in
getsockname(3SOCKET). Otherwise,
-1 is returned and
errno is set to ENOSYS to indicate that the library call could not be
injected.
ERRORS
For the full list of errors see the
ERRORS section in
getsockname(3SOCKET).
The
pr_getsockname() function will fail if:
ENOSYS An error occurred while trying to invoke the agent LWP
and inject a library call in the process handle
P or the
process handle
P does not support library call
injection.
