NAME
getpeername - get name of connected peer

SYNOPSIS
getpeername(s, name, namelen)
int s;
struct sockaddr *name;
int *namelen;

DESCRIPTION
Getpeername returns the name of the peer connected to socket s.
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). The name is truncated if the
buffer provided is too small.

DIAGNOSTICS
A 0 is returned if the call succeeds, -1 if it fails.

ERRORS
The call succeeds unless:

[EBADF] The argument s is not a valid 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 name parameter points to memory not in a valid
part of the process address space.
