Function Documentation

void caif_client_register_refcnt	(	struct cflayer *	adapt_layer,
		void(*)(struct cflayer *lyr)	hold,
		void(*)(struct cflayer *lyr)	put
	)

caif_client_register_refcnt - register ref-count functions provided by client.

: Client layer using CAIF Stack. : Function provided by client layer increasing ref-count : Function provided by client layer decreasing ref-count

Client of the CAIF Stack must register functions for reference counting. These functions are called by the CAIF Stack for every upstream packet, and must therefore be implemented efficiently.

Client should call caif_free_client when reference count degrease to zero.

void caif_free_client

(

struct cflayer *

adap_layer

)

caif_free_client - Free memory used to manage the client in the CAIF Stack.

: Client layer to be removed.

This function must be called from client layer in order to free memory. Caller must guarantee that no packets are in flight upstream when calling this function.
