Net-Relative Callback Methods

Services that use network address resources might require that start or stop steps be carried out in a particular order relative to the network address configuration. The following optional callback methods, Prenet_start and Postnet_stop, enable a resource type implementation to carry out special startup and shutdown actions before and after a related network address is configured or unconfigured.

Prenet_start

This optional method is called to carry out special startup actions before network addresses in the same resource group are configured.

Postnet_stop

This optional method is called to carry out special shutdown actions after network addresses in the same resource group are configured down.
