vsig(1F)      (Form and Menu Language Interpreter Utilities)       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 2 in the Programmer's Guide: System
         Services and Application Packaging Tools), 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 will flush 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.
