.TH fmt_ip4 3
.SH NAME
fmt_ip4 \- write a formatted ASCII representation of an IPv4 number
.SH SYNTAX
.B #include <ip4.h>
unsigned int \fBfmt_ip4\fP(char *\fIdest\fR,const char \fIip\fR[4]);
.SH DESCRIPTION
fmt_ip4 formats an IPv4 number in dotted-decimal ASCII representation
from \fIip\fR and writes the result into \fIdest\fR. It returns the
number of bytes written.
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ip4 returns the number
of bytes it would have written.
fmt_ip4 does not append \\0.
For convenience, ip4.h defines the integer IP4_FMT to be big enough to
contain every possible fmt_ip4 output plus \\0.
.SH EXAMPLE
#include <ip4.h>
char buf[IP4_FMT];
char ip[4];
buf[fmt_ip4(buf,ip)]=0;

.TH fmt_ip6 3
.SH NAME
fmt_ip6 \- write a formatted ASCII representation of an IPv6 number
.SH SYNTAX
.B #include <ip6.h>
unsigned int \fBfmt_ip6\fP(char *\fIdest\fR,const char \fIip\fR[16]);
.SH DESCRIPTION
fmt_ip6 formats an IPv6 number in ASCII representation from \fIip\fR and
writes the result into \fIdest\fR. It returns the number of bytes
written.
fmt_ip6 will apply "::" compression to the output.
If \fIip\fR is an IPv4-mapped IPv6 address, fmt_ip6 will output the last
4 bytes as IPv4 number in dotted-decimal notation.
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ip6 returns the number
of bytes it would have written.
fmt_ip6 does not append \\0.
For convenience, ip6.h defines the integer IP6_FMT to be big enough to
