DESCRIPTION
       The  popen()  function opens a process by creating a pipe,
       forking, and invoking the shell.  Since a pipe is by defi-
       nition  unidirectional, the type argument may specify only
       reading or writing, not both; the resulting stream is cor-
       respondingly read-only or write-only.
