After the specified number of minutes, a message is written to the user’s stderr. If the optional message argument is not specified, the default message is: WARNING: You have exceeded the maximum allowed session time.
Internally, this feature makes use of the new read-only policy variables runtimewarn and runtimewarnmsg to communicate the details from the policy server to the run host.
This feature might typically be used to warn a user of an upcoming timeout specified by the runtimelimit variable.
This feature may also be used with the new runtimewarnlog() procedure described below.
runtimewarn( minutes [, message] );
|Minutes||Required positive integer specifying the timeout in minutes.|
|Message||Optional string specifying a message to issue to the user on stderr.|
runtimewarn(20); runtimewarn(20, "Warning, your session will expire soon!");
