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

NAME


pr_getsockname - inject getsockname library call into victim process

SYNOPSIS


Process Control Library (libproc, -lproc)
#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.
