Hi all,
I have some doubts in selecting the interface to transfer packets and receive the packets.

I'd like to specify a different build and deployment path for files, by default the same path is used for both build and install, I wasn't able to find a way to make these different. With Solaris pkgadd, one can specify different paths in prototype, so I would assume something like that is possible... (0 Replies)

gen_udp(3erl) Erlang Module Definition gen_udp(3erl)NAME
gen_udp - Interface to UDP sockets
DESCRIPTION
The gen_udp module provides functions for communicating with sockets using the UDP protocol.
DATA TYPES
ip_address()
see inet(3erl)
posix()
see inet(3erl)
socket()
as returned by open/1,2
EXPORTS
open(Port) -> {ok, Socket} | {error, Reason}
open(Port, Options) -> {ok, Socket} | {error, Reason}
Types Port = 0..65535
Options = [Opt]
Opt -- see below
Socket = socket()
Reason = posix()
Associates a UDP port number ( Port ) with the calling process.
The available options are:
list :
Received Packet is delivered as a list.
binary :
Received Packet is delivered as a binary.
{ip, ip_address()} :
If the host has several network interfaces, this option specifies which one to use.
{fd, int()} :
If a socket has somehow been opened without using gen_udp , use this option to pass the file descriptor for it.
inet6 :
Set up the socket for IPv6.
inet :
Set up the socket for IPv4.
Opt :
See inet:setopts/2 .
The returned socket Socket is used to send packets from this port with send/4 . When UDP packets arrive at the opened port, they are
delivered as messages:
{udp, Socket, IP, InPortNo, Packet}
Note that arriving UDP packets that are longer than the receive buffer option specifies, might be truncated without warning.
IP and InPortNo define the address from which Packet came. Packet is a list of bytes if the option list was specified. Packet is a
binary if the option binary was specified.
Default value for the receive buffer option is {recbuf, 8192} .
If Port == 0 , the underlying OS assigns a free UDP port, use inet:port/1 to retrieve it.
send(Socket, Address, Port, Packet) -> ok | {error, Reason}
Types Socket = socket()
Address = string() | atom() | ip_address()
Port = 0..65535
Packet = [char()] | binary()
Reason = not_owner | posix()
Sends a packet to the specified address and port. The Address argument can be either a hostname, or an IP address.
recv(Socket, Length) -> {ok, {Address, Port, Packet}} | {error, Reason}
recv(Socket, Length, Timeout) -> {ok, {Address, Port, Packet}} | {error, Reason}
Types Socket = socket()
Length = int()
Address = ip_address()
Port = 0..65535
Packet = [char()] | binary()
Timeout = int() | infinity
Reason = not_owner | posix()
This function receives a packet from a socket in passive mode.
The optional Timeout parameter specifies a timeout in milliseconds. The default value is infinity .
controlling_process(Socket, Pid) -> ok
Types Socket = socket()
Pid = pid()
Assigns a new controlling process Pid to Socket . The controlling process is the process which receives messages from the socket.
close(Socket) -> ok | {error, Reason}
Types Socket = socket()
Reason = not_owner | posix()
Closes a UDP socket.
