Hi!
----
Attached is a small patch ("ksh93_libcmd_fds_ipv6_001.diff.txt") to add
IPv6 support to ksh93/libcmd's "fds" command. The patch fixes some minor
other issues, too - including that it now correctly handles |OPEN_MAX|
and supports OSes where |getsockopt(i, SOL_SOCKET, SO_PROTOTYPE, ...)|
is not (yet) supported (e.g. Solaris <= 10) ...
----
Bye,
Roland
