> What is semtool?

semtool - A utility for tinkering with semaphores

USAGE:  semtool  (c)reate <semcount>
                 (l)ock <sem #>
                 (u)nlock <sem #>
                 (d)elete
                 (m)ode <mode>

  It comes in some package available through the Cygwin's installer. I
do not understand how to use it.

  The persistence of the semaphore also works for you?

  For me, using the unpatched version, (not the CVS version), the
persistence works some times only. At other times the semaphore
disappears with the Control c.
