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

NAME

pr_getpeername - inject getpeername library call into victim process

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

int
pr_getpeername(struct ps_prochandle *P, int sock, struct sockaddr *name,
socklen_t *namelen);

DESCRIPTION

The pr_getpeername() function injects the getpeername(3SOCKET) library 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 getpeername(3SOCKET) on the
currently running process.

The arguments sock, name, and namelen have the same meaning as in
getpeername(3SOCKET). See getpeername(3SOCKET) for the full description
and purpose of the getpeername library call and its arguments.

The pr_getpeername() 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_getpeername() function's return value is
that described in getpeername(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 getpeername(3SOCKET).

The pr_getpeername() 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.

INTERFACE STABILITY

Uncommitted
