If var is specified, saves the value of var.
::cisco::eem::event_register_none
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
set testvar 123
if {[catch {context_save TESTCTX testvar} errmsg]} {
action_syslog msg "context_save failed: $errmsg"
} else {
action_syslog msg "context_save succeeded"
}
Example 2: Retrieve
If var is specified and index_if_array is not specified, or if index_if_array is specified but var is a scalar
variable, retrieves the value of var.
::cisco::eem::event_register_none
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
if {[catch {set testvar [context_retrieve TESTCTX testvar]} errmsg]} {
action_syslog msg "context_retrieve failed: $errmsg"
} else {
action_syslog msg "context_retrieve succeeded"
}
if {[info exists testvar]} {
action_syslog msg "testvar exists and is $testvar"
} else {
action_syslog msg "testvar does not exist"
}
Example 3: Save
If var is specified, saves the value of var even if it is an array.
::cisco::eem::event_register_none
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
array set testvar "testvar1 ok testvar2 not_ok"
if {[catch {context_save TESTCTX testvar} errmsg]} {
