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
       Solaris DDI specific (Solaris 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.
