Description

DP_ReleaseConsumerContext deselects the currently active consumer and context pair, reactivating the consumer and context pair that was active before it.
This routine in combination with DP_SelectConsumerContext allows the selection/deselection of a consumer and it's active context to be performed atomically. If one of the deselection actions fails, the other will be reverted automatically.
Most consumers will use this routine to deselect itself and it's associated context from the provider when they no longer need access to the provider.
