Why not redirect the ping output to a file,then read the
file to get your info?(Dont forget to delete the file)

There's no portable way to do I/O redirection either.

IOW, as has been pointed out a number of times already, doing this
requires platform-specific code, which indicates that it should be
discussed where the particular platform(s) in question are topical.

It even depends on the particular implementation of ping sometimes, as
different versions can have differing output. When I did a task like
this many moons ago, the ping we had on our HPUX systems was different
from the one I'd previously used on Solaris, so I had to alter the
parsing routine (I used popen(), but that's irrelevant to this group).

Absolutely.
