new features:
added generic socket addresses: SOCKET-CONNECT, SOCKET-LISTEN,
SOCKET-SENDTO, SOCKET-RECVFROM, SOCKET-RECV, SOCKET-DATAGRAM allow
protocol independent socket handling; all parameters are explicitely
specified as numbers or hex data
added address options ioctl-void, ioctl-int, ioctl-intp, ioctl-string,
ioctl-bin for generic ioctl() calls.
added address options setsockopt-int, setsockopt-bin, and
setsockopt-string
so-type now only affect the socket() and socketpair() calls, not the
name resolution. so-type and so-prototype can be applied to all socket
based addresses.
new address option "escape" allows to break a socat instance even when
raw terminal mode prevents ^C etc.
@ -31,10 +46,6 @@ new features:
new address options ipv6-tclass and ipv6-unicast-hops set the related
socket options.
so-type now only affect the socket() and socketpair() calls, not the

based addresses.
corrections:
some raw IP and UNIX datagram modes failed on BSD systems

third argument. This option allows to utilize ioctls that are not
explicitely implemented in socat.

label(OPTION_SETSOCKOPT_INT)dit(bf(tt(setsockopt-int=<level>:<optname>:<optval>)))
Invokes tt(setsockopt()) for the socket with the given parameters. tt(level)
[link(int)(TYPE_INT)] is used as second argument to tt(setsockopt()) and
specifies the layer, e.g. SOL_TCP for TCP (6 on Linux), or SOL_SOCKET for
the socket layer (1 on Linux). tt(optname) [link(int)(TYPE_INT)] is the
third argument to tt(setsockopt()) and tells which socket option is to be
set. For the actual numbers you might have to look up the appropriate include
files of your system. The 4th tt(setsockopt()) parameter, tt(value)
[link(int)(TYPE_INT)], is passed to the function per pointer, and for the
length parameter sizeof(int) is taken implicitely.
label(OPTION_SETSOCKOPT_BIN)dit(bf(tt(setsockopt-bin=<level>:<optname>:<optval>)))
Like tt(setsockopt-int), but <optval> must be provided in
link(dalan)(TYPE_DATA) format and specifies an arbitrary sequence of bytes;
the length parameter is automatically derived from the data.
