NET_PROTOCOL_WALK 9F "May 1, 2008"
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.
