Note:

  Check out the directory ../with-c for this in
  C-only, i.e., no system(3) or zsh, instead
  fprintf(3) - that solution is better (faster) than
  this.


This directory contains the programs 'cont-from-c.c'
and 'stop-from-c.c'.

Those programs compile into 'cont-from-c' and
'stop-from-c'.

If invoked, they call '../cont' and '../stop'; they do
this with system(3).

If ==> is the compilation through the Makefile, and
   --> is the execution of the result binaries,
then:

    cont-from-c.c ==> cont-from-c --> ../cont
    stop-from-c.c ==> stop-from c --> ../stop
