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

       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 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.
