net_phylookup(9F)					   Kernel Functions for Drivers 					 net_phylookup(9F)

NAME

       net_phylookup - determine if a network interface name exists for a network protocol

SYNOPSIS

       #include <sys/neti.h>

       phy_if_t net_phylookup(const net_data_t net, const char *name);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

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

       name    name of the network interface to find.

DESCRIPTION

       The net_phylookup() function attempts to resolve the interface 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 net_phylookup() function returns -1 if it is not supported by the network  protocol,  and 0 if the named  network  interface  does  not
       exist  (or is otherwise	unknown).  Otherwise, it returns  a  value  greater  than 0 representing a network interface that currently exists
       within the scope of this network protocol.

CONTEXT

       The net_phylookup() function may be called from user,  kernel, or interrupt context.

NAME

       net_phygetnext - search through the current list of network interfaces

SYNOPSIS

       #include <sys/neti.h>

       phy_if_t net_phygetnext(const net_data_t net, const phy_if_t ifp);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

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

       ifp    value returned from a successful call to this function or net_phylookup(9F).

DESCRIPTION

       The net_phygetnext() function searches through all of the network interfaces that a network protocol "owns". To start searching through all
       of the interfaces owned by a protocol, a value of 0 should be passed through as the value of ifp. When 0 is returned by this function,  the
       last of the interfaces owned by this protocol has been reached.

       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.

EXAMPLES

	    net_data_t net;
	     phy_if_t ifp;
	     char buffer[32];

	     net = net_protocol_lookup("inet");

	     if (net != NULL) {
		  for (ifp = net_phygetnext(net, 0); ifp != 0;
		       ifp = net_phygetnext(net, ifp)) {
		       /* Do something with ifp */
		       if (net_getifname(net, ifp, buffer,
			    sizeof(buffer) >= 0)
			     printf("Interface %s0, buffer);
		   }
	       }

RETURN VALUES

       The net_phygetnext() function returns -1 if it is not supported by the network  protocol or 0 if an attempt to go beyond the  last  network
       interface  is  made. Otherwise, it returns  a  value representing a network interface.

CONTEXT

       The net_phygetnext() function may be called from user,  kernel, or interrupt context.
