vsig(1F)                                                    vsig(1F)


       NAME
             vsig - synchronize a co-process with the controlling FMLI
             application

       SYNOPSIS
             vsig

       DESCRIPTION
             The vsig executable sends a SIGUSR2 signal to the controlling
             FMLI process.  This signal/alarm causes FMLI to execute the
             FMLI built-in command checkworld (see Chapter 3 in Character
             User Interface Programming), which causes all posted objects
             with a reread descriptor evaluating to TRUE to be reread.
             vsig takes no arguments.

       EXAMPLES
             The following is a segment of a shell program:

                   echo "Sending this string to an FMLI process"
                   vsig

             The vsig executable flushes the output buffer before it sends
             the SIGUSR2 signal to make sure the string is actually in the
             pipe created by the cocreate function.

       NOTES
             Because vsig synchronizes with FMLI, it should be used rather
             than kill to send a SIGUSR2 signal to FMLI.
