NAME
       if_indextoname - Map an interface index to an interface name

SYNOPSIS
       #include <net/if.h>

       char *if_indextoname(
	       unsigned int ifindex,
	       char *ifname );

LIBRARY
       Standard C Library (libc)

PARAMETERS
       Specifies  the  index  number.	Points	to a buffer, IFNAMSIZ bytes in
       length, into which the function will place the interface name. IFNAMSIZ
       is defined in <net/if.h>.

DESCRIPTION
       The  if_indextoname()  function	maps  an interface index number to its
       corresponding interface name.

RETURN VALUES
       Upon successful conversion, the if_indextoname() function  returns  the
       value  specified	 in the ifname parameter, which points the buffer that
       now contains the interface name.	 If no interface name  corresponds  to
       the index, it returns a NULL pointer.

SEE ALSO
       Functions: if_freenameindex(3), if_nameindex(3), if_nametoindex(3).
