HPUX getpeername[2]

getpeername(2) getpeername(2)
NAME
getpeername - get address of connected peer
SYNOPSIS
#include <sys/socket.h>
AF_CCITT only:
#include <x25/x25addrstr.h>
int getpeername(int s, void *addr, int *addrlen);
DESCRIPTION
getpeername() returns the address of the peer socket connected to the
socket indicated by s, where s is a socket descriptor. addr points to
a socket address structure in which this address is returned. addrlen
points to an object of type int, which should be initialized to
indicate the size of the address structure. On return, it contains
the actual size of the address returned (in bytes). If addr does not
point to enough space to contain the whole address of the peer, only
the first addrlen bytes of the address are returned.
AF_CCITT only:
The addr struct contains the X.25 addressing information of the remote
peer socket connected to socket s. However, the x25ifname[] field of
the addr struct contains the name of the local X.25 interface through
which the call arrived.
RETURN VALUE
Upon successful completion, getpeername() returns 0; otherwise it
returns -1 and sets errno to indicate the error.
ERRORS
getpeername() fails if any of the following conditions are
encountered:
[EBADF] The argument s is not a valid file
descriptor.
[ENOTSOCK] The argument s is a file, not a socket.
[ENOTCONN] The socket is not connected.
[ENOBUFS] Insufficient resources were available in the
system to perform the operation.
[EFAULT] The addr or addrlen parameters are not valid
pointers.
[EINVAL] The socket has been shut down.
