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.
