ETHERS(3Y)							    ETHERS(3Y)

NAME
     ether_ntoa, ether_aton, ether_ntohost, ether_hostton, ether_line -
     ethernet address mapping operations

SYNOPSIS
     struct ether_addr {
	 unsigned char	ether_addr_octet[6];
     };
     char *ether_ntoa(struct ether_addr *e);
     struct ether_addr *ether_aton(char *s);
     int ether_ntohost(char *hostname, struct ether_addr *e);
     int ether_hostton(char *hostname, struct ether_addr *e);
     int ether_line(char *l, struct ether_addr *e, char *hostname)

DESCRIPTION
     These routines are useful for mapping 48 bit ethernet numbers to their
     ASCII representations or their corresponding host names, and vice versa.

     The function ether_ntoa converts a 48-bit ethernet number pointed to by e
     to its standard ACSII representation; it returns a pointer to the ASCII
     string.  The representation is of the form: ``x:x:x:x:x:x'' where x is a
     hexadecimal number between 0 and ff.  The function ether_aton converts an
     ASCII string in the standard representation back to a 48 bit ethernet
     number;  the function returns NULL if the string cannot be scanned
     successfully.

     The function ether_ntohost maps an ethernet number (pointed to by e) to
     its associated hostname.  The string pointed to by hostname must be long
     enough to hold the hostname and a null character.	The function returns
     zero upon success and non-zero upon failure.  Inversely, the function
     ether_hostton maps a hostname string to its corresponding ethernet
     number; the function modifies the ethernet number pointed to by e.	 The
     function also returns zero upon success and non-zero upon failure.

     The function ether_line scans a line (pointed to by l) and sets the
     hostname and the ethernet number (pointed to by e).  The string pointed
     to by hostname must be long enough to hold the hostname and a null
     character.	 The function returns zero upon success and non-zero upon
     failure.  The format of the scanned line is described by ethers(4).
