NAME
       eipconv, parseip, parseether, myipaddr, myetheraddr, maskip, equivip - Internet protocol

SYNOPSIS
       #include <u.h>
       #include <libc.h>
       #include <ip.h>

       int  eipconv(void *o, int f1, int f2, int f3, int chr)

       int  parseip(uchar *ipaddr, char *str)

       int  parseether(uchar *eaddr, char *str)

       int  myipaddr(uchar *ipaddr, char *net)

       int  myetheraddr(uchar *eaddr, char *net)

       void maskip(uchar *from, uchar *mask, uchar *to)

       int  equivip(uchar *ipaddr1, uchar *ipaddr2)

DESCRIPTION
       These routines are used by Internet Protocol (IP) programs to manipulate IP and Ethernet addresses.  IP addresses are stored as a string of
       4 unsigned chars, Ethernet addresses as 6 unsigned chars.  The string representation of IP addresses is (up to) 4 decimal integers  from  0
       to 255 separated by periods.  The string representation of Ethernet addresses is exactly 12 hexadecimal digits.

       Eipconv is a print(2) formatter for Ethernet (verb E) and Internet protocol (verb I) addresses.

       Parseip	converts  a  string  pointed  to by str to a 4-byte IP address starting at ipaddr.  Myipaddr reads the IP address string from file
       /net/1/local and parses it into ipaddr.	Both routines return a negative number on errors.

       Parseether converts a string pointed to by str to a 6 byte Ethernet address starting at eaddr.	Myetheraddr  reads  the  Ethernet  address
       string from file net/1/stats and parses it into eaddr.  Both routines return a negative number on errors.

       Maskip places the bit-wise AND of the IP addresses pointed to by its first two arguments into the buffer pointed to by the third.

       Equivip returns non-zero if the IP addresses pointed to by its two arguments are equal.
