label(OPTION_PROTOCOL_FAMILY)dit(bf(tt(pf=<string>)))
Forces the use of the specified IP version. <string> can be
something like "ip4" or "ip6".
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)] specifies the second argument to tt(setsockopt())
which specifies the layer, e.g. SOL_TCP (=6 on Linux) for TCP, or SOL_SOCKET
(=1 on Linux) for the socket layer. tt(optname) [link(int)(TYPE_INT)]
selects the third argument to tt(setsockopt()) option. For the actual
integer values you might have to look up the appropriate include file of
your system. The 4th tt(setsockopt()) parameter, tt(value)
[link(int)(TYPE_INT)], is passed to the function per pointer, and the length
parameter to the tt(setsockopt()) call is derived from this type.
label(OPTION_SETSOCKOPT_BIN)dit(bf(tt(setsockopt-bin=<level>:<optname>:<optval>)))
Like tt(setsockopt-int), but <optval> is expected in link(dalan)(TYPE_DATA)
format and specifies an arbitrary sequence of bytes.
label(OPTION_SETSOCKOPT_STRING)dit(bf(tt(setsockopt-string=<level>:<optname>:<optval>)))
Like tt(setsockopt-int), but <optval> must be a link(string)(TYPE_STRING).
This string is passed to the function with trailing null character.
