I have a problem using signal SIGUSR2
hi
I have created a application which uses SIGUSR2. It send this signal to server and waits for signal SIGUSR2 from server after server performing some operation server sends SIGUSR2 back to the application. The application then quits.
This works fine which ran from terminal , but when I use this application in a shell script, shrll script stop execution after execution of this application with USER SIGNAL 2 Message.
Is is a normal behaviour, is tere some way to stop this message
kindly some one clarify me with this
with hope

vsig
vsig(1F) 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 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.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWesu |
+-----------------------------+-----------------------------+
SEE ALSO
coproc(1F), kill(1), kill(2), signal(3C), attributes(5)
NOTES
Because vsig synchronize with FMLI, it should be used rather than kill to send a SIGUSR2 signal to FMLI.
