Variables

var Author = ""

Author is used for the module info

var CallbackTimeout = time.Duration(10) * time.Millisecond

CallbackTimeout is the duration each callback has to return. This can be changed at the beginning.

License is used for the module info

var Name = "go_neb_broker"

Name is used for some default logs

var NebModuleDeinitHook func(flags, reason int) int

NebModuleDeinitHook gives you access to the flags and reason which the core passes to the brokers, when it's unloading your code. This function will be called at the end of the deinit function return Ok if everything went well

var NebModuleInitHook func(flags int, args string) int

NebModuleInitHook gives you access to the flags and args which the core passes to the brokers, when it's loading your code. This function will be called at the end of the init function return Ok if everything went well
