NAME
net_protocol_lookup - locate an implementation of a network
layer protocolSYNOPSIS
#include
net_data_t net_protocol_lookup(netid_t id, const char *protocol);
INTERFACE LEVEL
Solaris DDI specific (Solaris 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 tonet_protocol_release(9F), after which it should no longer be
treated as valid. The protocol must be a registered name of a network protocolthat 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 refer-
enced. 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.ATTRIBUTES
