NET_PROTOCOL_LOOKUP(9F) Kernel Functions for Drivers
NAME
net_protocol_lookup - locate an implementation of a network layer
protocol
SYNOPSIS
#include <sys/neti.h>
net_handle_t net_protocol_lookup(
netid_t id,
const char *
protocol);
INTERFACE LEVEL
illumos DDI specific (illumos DDI).
PARAMETERS
id network instance identifier.
family name of the network protocol to find.
DESCRIPTION
The
net_protocol_lookup() function attempts to locate a data
structure that defines what capabilities it is exporting through this
interface. The value returned by this call is guaranteed to be valid
until it is passed into a call to
net_protocol_release(9F), after
which it should no longer be treated as valid.
The protocol must be a registered name of a network protocol that has
been registered. The symbols
NHF_INET and
NHF_INET6 should be passed
to
net_protocol_lookup() as the protocol name to gain access to
either
IPv4 or
IPv6 respectively.
RETURN VALUES
The
net_protocol_lookup() function returns
NULL if it does not find
any knowledge about the network protocol referenced. Otherwise, it
returns a value that can be used with other calls in this framework.
CONTEXT
The
net_protocol_lookup() function may be called from user, kernel,
or interrupt context.
