NET_GETIFNAME(9F) Kernel Functions for Drivers NET_GETIFNAME(9F)
NAME
net_getifname - determine the name given to a network interface
SYNOPSIS
#include <sys/neti.h>
int net_getifname(
const net_data_t net,
const phy_if_t ifp,
char *buffer,
size_t buflen);
INTERFACE LEVEL
illumos DDI specific (illumos DDI).
PARAMETERS
net value returned from a successful call to
net_protocol_lookup(9F).
ifp value returned from a successful call to
net_phylookup(9F) or
net_phygetnext(9F).
buffer pointer to the buffer in which to write the interface name.
buflen size of the buffer in which to store the interface name.
DESCRIPTION
The
net_getifname() function copies the name of the network interface
into the buffer provided. The name will always be null-terminated. If
the buffer is too small to fit both the interface name and the null-
terminated name, the name in the buffer is truncated to fit. See
net_phygetnext(9F) for an example on how to use this function.
RETURN VALUES
The
net_getifname() function returns:
-1 The network protocol does not support this function.
0 Successful completion.
1 Unsuccessful.
CONTEXT
The
net_getifname() function may be called from user, kernel, or
interrupt context.
