net_phylookup - determine if a network interface name exists for a network
protocol
#include <sys/neti.h>
phy_if_t net_phylookup(const net_data_t net, const char *name);
illumos DDI specific (illumos DDI).
net
name
name of the network interface to find.
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.
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.
The net_phylookup() function may be called from user, kernel, or
interrupt context.
