NET_PHYLOOKUP 9F "May 1, 2008"
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
illumos DDI specific (illumos 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.
