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.
