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. SunOS 5.8 Last change: 5 Jul 1990 1
