socket_getsockname

SOCKET_GETSOCKNAME(3)							 1						     SOCKET_GETSOCKNAME(3)

socket_getsockname  -  Queries	the local side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on
its type

SYNOPSIS

       bool socket_getsockname (resource  $socket, string  &$addr, [int  &$port])

DESCRIPTION

       Note

	      socket_getsockname(3) should  not  be  used  with  AF_UNIX  sockets  created  with  socket_connect(3).  Only  sockets  created  with
	      socket_accept(3) or a primary server socket following a call to socket_bind(3) will return meaningful values.

PARAMETERS

	      o $socket
		- A valid socket resource created with socket_create(3) or socket_accept(3).

	      o $addr
		-  If the given socket is of type AF_INET or AF_INET6, socket_getsockname(3) will return the local IP address in appropriate nota-
		tion (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_getsockname(3) will return the Unix filesystem path (e.g.  /var/run/dae-
		mon.sock) in the $address parameter.

	      o $port
		- If provided, this will hold the associated port.

RETURN VALUES

	Returns TRUE on success or FALSE on failure. socket_getsockname(3) 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.

SEE ALSO

       socket_getpeername(3), socket_last_error(3), socket_strerror(3).
