6 fmt_ip6 - write a formatted ASCII representation of an IPv6 number
7
9 #include <ip6.h>
10
11 unsigned int fmt_ip6(char *dest,const char ip[16]);
12
14 fmt_ip6 formats an IPv6 number in ASCII representation from ip and
15 writes the result into dest. It returns the number of bytes written.
16
17 fmt_ip6 will apply "::" compression to the output.
18
19 If ip is an IPv4-mapped IPv6 address, fmt_ip6 will output the last 4
20 bytes as IPv4 number in dotted-decimal notation.
21
22 If dest equals FMT_LEN (i.e. is zero), fmt_ip6 returns the number of
23 bytes it would have written.
24
25 fmt_ip6 does not append \0.
26
27 For convenience, ip6.h defines the integer IP6_FMT to be big enough to
28 contain every possible fmt_ip6 output plus \0.
