NAME
getsockname - get socket name
SYNOPSIS
#include <sys/socket.h>
int getsockname(int s , struct sockaddr * name , int *
namelen
DESCRIPTION
Getsockname returns the current name for the specified
socket. The namelen parameter should be initialized to
indicate the amount of space pointed to by name. On return
it contains the actual size of the name returned (in bytes).
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and
errno is set appropriately. A 0 is returned if the call
succeeds, -1 if it fails.
ERRORS
EBADF The argument s is not a valid descriptor.
ENOTSOCK
The argument s is a file, not a socket.
ENOBUFS Insufficient resources were available in the system
to perform the operation.
EFAULT The name parameter points to memory not in a valid
part of the process address space.
CONFORMING TO

codes.
