15 \fBnet_handle_t\fR \fBnet_protocol_lookup\fR(\fBnetid_t\fR \fIid\fR, \fBconst\fR \fBchar\fR *\fIprotocol\fR);
21 Solaris DDI specific (Solaris DDI).
29 network instance identifier.
38 name of the network protocol to find.
44 The \fBnet_protocol_lookup()\fR function attempts to locate a data structure
45 that defines what capabilities it is exporting through this interface. The
46 value returned by this call is guaranteed to be valid until it is passed into a
47 call to \fBnet_protocol_release\fR(9F), after which it should no longer be
51 The protocol must be a registered name of a network protocol that has been
52 registered. The symbols \fBNHF_INET\fR and \fBNHF_INET6\fR should be passed to
53 \fBnet_protocol_lookup()\fR as the protocol name to gain access to either
54 \fBIPv4\fR or \fBIPv6\fR respectively.
58 The \fBnet_protocol_lookup()\fR function returns \fBNULL\fR if it does not find
59 any knowledge about the network protocol referenced. Otherwise, it returns a
60 value that can be used with other calls in this framework.
64 The \fBnet_protocol_lookup()\fR function may be called from user, kernel, or
