label(ADDRESS_UNNAMED_PIPE)dit(bf(tt(PIPE)))
Creates an unnamed pipe and uses it for reading and writing. It works as an
echo, because everything written
to it appeares immediately as read data.nl()
echo, because everything written to it appeares immediately as read
data.nl()
Note: When socat tries to write more bytes than the pipe can queue (Linux
2.4: 2048 bytes), socat might block. Consider, e.g., using
option code(-b 2048) nl()
Option groups: link(FD)(GROUP_FD) nl()

label(ADDRESS_SOCKETPAIR)dit(bf(tt(SOCKETPAIR)))
Creates a socketpair and uses it for reading and writing. It works as an
echo, because everything written to it appeares immediately as read
data. The default socket type is datagram, so it keeps packet boundaries.
nl()
Option groups: link(FD)(GROUP_FD) nl()
Useful options:
link(socktype)(OPTION_SO_TYPE)nl()

Connects to an HTTP proxy server on port 8080 using TCP/IP version 4 or 6
