8Socket, sockaddr_in, sockaddr_un, inet_aton, inet_ntoa - load the C socket.h defines and structure manipulators
9
10=head1 SYNOPSIS
11
12 use Socket;
13
14 $proto = getprotobyname('udp');
15 socket(Socket_Handle, PF_INET, SOCK_DGRAM, $proto);
16 $iaddr = gethostbyname('hishost.com');
17 $port = getservbyname('time', 'udp');
18 $sin = sockaddr_in($port, $iaddr);
19 send(Socket_Handle, 0, 0, $sin);
20
21 $proto = getprotobyname('tcp');
22 socket(Socket_Handle, PF_INET, SOCK_STREAM, $proto);
23 $port = getservbyname('smtp', 'tcp');
24 $sin = sockaddr_in($port,inet_aton("127.1"));
25 $sin = sockaddr_in(7,inet_aton("localhost"));
26 $sin = sockaddr_in(7,INADDR_LOOPBACK);
27 connect(Socket_Handle,$sin);
28
29 ($port, $iaddr) = sockaddr_in(getpeername(Socket_Handle));
30 $peer_host = gethostbyaddr($iaddr, AF_INET);
31 $peer_addr = inet_ntoa($iaddr);
32
33 $proto = getprotobyname('tcp');
34 socket(Socket_Handle, PF_UNIX, SOCK_STREAM, $proto);
35 unlink('/var/run/usock');
36 $sun = sockaddr_un('/var/run/usock');
37 connect(Socket_Handle,$sun);
38
39=head1 DESCRIPTION
40
41This module is just a translation of the C F<socket.h> file.
42Unlike the old mechanism of requiring a translated F<socket.ph>
43file, this uses the B<h2xs> program (see the Perl source distribution)
44and your native C compiler. This means that it has a
45far more likely chance of getting the numbers right. This includes
46all of the commonly used pound-defines like AF_INET, SOCK_STREAM, etc.
47
48Also, some common socket "newline" constants are provided: the
49constants C<CR>, C<LF>, and C<CRLF>, as well as C<$CR>, C<$LF>, and
50C<$CRLF>, which map to C<\015>, C<\012>, and C<\015\012>. If you do
51not want to use the literal characters in your programs, then use
52the constants provided here. They are not exported by default, but can
53be imported individually, and with the C<:crlf> export tag:
54
55 use Socket qw(:DEFAULT :crlf);
56
57In addition, some structure manipulation functions are available:
58
59=over 4
60
61=item inet_aton HOSTNAME
62
63Takes a string giving the name of a host, and translates that to an
64opaque string (if programming in C, struct in_addr). Takes arguments
65of both the 'rtfm.mit.edu' type and '18.181.0.24'. If the host name
66cannot be resolved, returns undef. For multi-homed hosts (hosts with
67more than one address), the first address found is returned.
68
69For portability do not assume that the result of inet_aton() is 32
70bits wide, in other words, that it would contain only the IPv4 address
71in network order.
72
73=item inet_ntoa IP_ADDRESS
74
75Takes a string (an opaque string as returned by inet_aton(),
76or a v-string representing the four octets of the IPv4 address in
77network order) and translates it into a string of the form 'd.d.d.d'
78where the 'd's are numbers less than 256 (the normal human-readable
79four dotted number notation for Internet addresses).
80
81=item INADDR_ANY
82
83Note: does not return a number, but a packed string.
84
85Returns the 4-byte wildcard ip address which specifies any
86of the hosts ip addresses. (A particular machine can have
87more than one ip address, each address corresponding to
88a particular network interface. This wildcard address
89allows you to bind to all of them simultaneously.)
90Normally equivalent to inet_aton('0.0.0.0').
91
92=item INADDR_BROADCAST
93
94Note: does not return a number, but a packed string.
95
96Returns the 4-byte 'this-lan' ip broadcast address.
97This can be useful for some protocols to solicit information
98from all servers on the same LAN cable.
99Normally equivalent to inet_aton('255.255.255.255').
100
101=item INADDR_LOOPBACK
102
103Note - does not return a number.
104
105Returns the 4-byte loopback address. Normally equivalent
106to inet_aton('localhost').
107
108=item INADDR_NONE
109
110Note - does not return a number.
111
112Returns the 4-byte 'invalid' ip address. Normally equivalent
113to inet_aton('255.255.255.255').
114
115=item sockaddr_family SOCKADDR
116
117Takes a sockaddr structure (as returned by pack_sockaddr_in(),
118pack_sockaddr_un() or the perl builtin functions getsockname() and
119getpeername()) and returns the address family tag. It will match the
120constant AF_INET for a sockaddr_in and AF_UNIX for a sockaddr_un. It
121can be used to figure out what unpacker to use for a sockaddr of
122unknown type.
123
124=item sockaddr_in PORT, ADDRESS
125
126=item sockaddr_in SOCKADDR_IN
127
128In a list context, unpacks its SOCKADDR_IN argument and returns an array
129consisting of (PORT, ADDRESS). In a scalar context, packs its (PORT,
130ADDRESS) arguments as a SOCKADDR_IN and returns it. If this is confusing,
131use pack_sockaddr_in() and unpack_sockaddr_in() explicitly.
132
133=item pack_sockaddr_in PORT, IP_ADDRESS
134
135Takes two arguments, a port number and an opaque string, IP_ADDRESS
136(as returned by inet_aton(), or a v-string). Returns the sockaddr_in
137structure with those arguments packed in with AF_INET filled in. For
138Internet domain sockets, this structure is normally what you need for
139the arguments in bind(), connect(), and send(), and is also returned
140by getpeername(), getsockname() and recv().
141
142=item unpack_sockaddr_in SOCKADDR_IN
143
144Takes a sockaddr_in structure (as returned by pack_sockaddr_in()) and
145returns an array of two elements: the port and an opaque string
146representing the IP address (you can use inet_ntoa() to convert the
147address to the four-dotted numeric format). Will croak if the
148structure does not have AF_INET in the right place.
149
150=item sockaddr_un PATHNAME
151
152=item sockaddr_un SOCKADDR_UN
153
154In a list context, unpacks its SOCKADDR_UN argument and returns an array
155consisting of (PATHNAME). In a scalar context, packs its PATHNAME
156arguments as a SOCKADDR_UN and returns it. If this is confusing, use
157pack_sockaddr_un() and unpack_sockaddr_un() explicitly.
158These are only supported if your system has E<lt>F<sys/un.h>E<gt>.
159
160=item pack_sockaddr_un PATH
161
162Takes one argument, a pathname. Returns the sockaddr_un structure with
163that path packed in with AF_UNIX filled in. For unix domain sockets, this
164structure is normally what you need for the arguments in bind(),
165connect(), and send(), and is also returned by getpeername(),
166getsockname() and recv().
167
168=item unpack_sockaddr_un SOCKADDR_UN
169
170Takes a sockaddr_un structure (as returned by pack_sockaddr_un())
171and returns the pathname. Will croak if the structure does not
172have AF_UNIX in the right place.
