6 fmt_ip4 - write a formatted ASCII representation of an IPv4 number
7
9 #include <ip4.h>
10
11 unsigned int fmt_ip4(char *dest,const char ip[4]);
12
14 fmt_ip4 formats an IPv4 number in dotted-decimal ASCII representation
15 from ip and writes the result into dest. It returns the number of bytes
16 written.
17
18 If dest equals FMT_LEN (i.e. is zero), fmt_ip4 returns the number of
19 bytes it would have written.
20
21 fmt_ip4 does not append \0.
22
23 For convenience, ip4.h defines the integer IP4_FMT to be big enough to
24 contain every possible fmt_ip4 output plus \0.
