-.SH DESCRIPTION
-The
-.BR if_nametoindex ()
-function returns the index of the network interface
-corresponding to the name

-The
-.BR if_indextoname ()
-function returns the name of the network interface

-on error, 0 is returned and
-.I errno
-is set to indicate the error.
-.P
-On success,
-.BR if_indextoname ()
-returns
-.IR ifname ;
-on error, NULL is returned and
-.I errno
-is set to indicate the error.
