NAME
     netphylookup - determine if a network interface name exists
     for a network protocol

SYNOPSIS
     #include 

     phyift netphylookup(const netdatat net, const char *name);


INTERFACE LEVEL
     Solaris DI specific (Solaris DI).

PARAMETERS
     net     value   returned   from   a   successful   call   to
             netprotocollookup(9F).


     name    name of the network interface to find.


DESCRIPTION
     The netphylookup() function attempts to resolve the  inter-
     face name passed in with the network protocol.


     When called successfully, the value  returned  represents  a
     network  interface  that  exists,  at  the time of the call,
     within the scope of the network  interface.  This  value  is
     only  guaranteed to be unique for a name within the scope of
     the network protocol.

RETURN VALUES
     The netphylookup() function returns -1 if it  is  not  sup-
     ported by the network  protocol,  and 0 if the named network
     interface does not exist (or is otherwise  unknown).  Other-
     wise,  it  returns  a  value  greater  than 0 representing a
     network interface that currently exists within the scope  of
     this network protocol.

CONTEXT
     The netphylookup() function may be called from user,   ker-
     nel, or interrupt context.
