vsig(1F)            (Form and Menu Language Interpreter)           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 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
     vsig synchronizes with FMLI. It should be used rather than kill to
     send a SIGUSR2 signal to FMLI.

SEE ALSO
     kill(1), coproc(1F), kill(2), signal(2).
