socket_getpeername — Queries the remote side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type
Queries the remote side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type.
socket
A Socket instance created with socket_create() or socket_accept().
address
If the given socket is of type AF_INET
or
AF_INET6
, socket_getpeername()
will return the peers (remote) IP address in
appropriate notation (e.g. 127.0.0.1
or
fe80::1
) in the address
parameter and, if the optional port
parameter is
present, also the associated port.
If the given socket is of type AF_UNIX
,
socket_getpeername() will return the Unix filesystem
path (e.g. /var/run/daemon.sock
) in the
address
parameter.
port
If given, this will hold the port associated to
address
.
Retorna true
em caso de sucesso ou false
em caso de falha. socket_getpeername() may also return
false
if the socket type is not any of AF_INET
,
AF_INET6
, or AF_UNIX
, in which
case the last socket error code is not updated.

Nota:
socket_getpeername() should not be used with
AF_UNIX
sockets created with socket_accept(). Only sockets created with socket_connect() or a primary server socket following a call to socket_bind() will return meaningful values.
Nota:
For having socket_getpeername() to return a meaningful value, the socket it is applied upon must of course be one for which the concept of "peer" makes sense.
