Set _cerrno
Yes
Sample Usage
Here is a similar example as above using this single command:
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
set i 1
while {1 == 1} {
# Start high performance policy loop
array set arr_einfo [event_reqinfo]
if {$_cerrno != 0} {
set result [format "component=%s; subsys err=%s; posix err=%s;\n%s" \
$_cerr_sub_num $_cerr_sub_err $_cerr_posix_err $_cerr_str]
error $result
}
action_syslog msg "event $i serviced" priority info
if {$i == 5} {
action_syslog msg "Exiting after servicing 5 events" priority info
exit 0
}
incr i
array set _event_state_arr [event_completion_with_wait status 0 refresh_vars 1]
if {$_event_state_arr(event_state) != 0} {
action_syslog msg "Exiting: failed event_state " \
" $event_state_arr(event_state)" priority info
exit 0
}
}
The running configuration output is the same as the event_publishTcl command.
