FMLI Commands                                            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  control-
     ling  FMLI process. This signal/alarm causes FMLI to execute
     the FMLI built-in command checkworld which causes all posted
     objects  with  a reread descriptor evaluating to  TRUE to be
     reread. vsig takes no arguments.

EXAMPLES
     Example 1 A sample output of vsig command.


     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 synchronize with FMLI, it should be used rather
     than kill to send a SIGUSR2 signal to FMLI.
