System() function

[Jonathan I. Kamens]

  I fail to see how this has anything to do with Unix internals.  It is
clearly a question about programming under Unix, which means that it clearly
belongs in comp.unix.programmer.

  I've cross-posted to comp.unix.programmer and directed followups there.

  Use popen("man cat | wc -c", "r"), which will return a FILE *, and you can
read the output of wc from the FILE *.  See popen(3).
