vsig(1F) FMLI Commands vsig(1F)NAMEvsig - synchronize a co-process with the controlling FMLI application
SYNOPSISvsigDESCRIPTION
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
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.
