NET_PROTOCOL_WALK(9F) Kernel Functions for Drivers NET_PROTOCOL_WALK(9F)


NAME


net_protocol_walk - step through the list of registered network protocols

SYNOPSIS


#include <sys/neti.h>

net_data_t *net_protocol_walk(net_data_t net);


INTERFACE LEVEL


illumos DDI specific (illumos DDI).

PARAMETERS


net
value returned from a successful call to net_protocol_lookup(9F).


DESCRIPTION


The net_protocol_walk() function walks through all of the network
protocols that have been registered with this interface. The initial call
to net_protocol_walk() should be made by passing in NULL as the value for
net. When this function returns NULL, the end of the list has been
reached.


A caller of net_protocol_walk() is required to walk through the entire
list of network protocols, until NULL is returned or, when finished with
using the value returned, pass it into a call to
net_protocol_release(9F).

RETURN VALUES


The net_protocol_walk() function returns NULL when the end of the list is
returned. Otherwise, it returns a non-NULL value as a token for being
passed into other function calls within this interface.

CONTEXT


The net_protocol_walk() function may be called from user, kernel, or
interrupt context.
