.TH fmt_ip6_flat 3
.SH NAME
fmt_ip6_flat \- write a formatted ASCII representation of an IPv6 number
.SH SYNTAX
.B #include <ip6.h>

unsigned int \fBfmt_ip6_flat\fP(char *\fIdest\fR,const char \fIip\fR[16]);
.SH DESCRIPTION
fmt_ip6_flat formats an IPv6 number in a flat ASCII representation from
\fIip\fR and writes the result into \fIdest\fR. It returns the number of
bytes written (always 32).

This representation does not contain colons and is meant to be easily
machine-readable.  Use fmt_ip6 for the normal (standard) representation.
This function is meant for places which use colons to separate fields
and thus have problems interpreting the standard IPv6 notation.

If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ip6_flat returns the
number of bytes it would have written.

fmt_ip6_flat does not append \\0.

For convenience, ip6.h defines the integer IP6_FMT to be big enough to
contain every possible fmt_ip6_flat output plus \\0.
.SH EXAMPLE
#include <ip6.h>

  char buf[IP6_FMT];
  char ip[16];
  buf[fmt_ip6_flat(buf,ip)]=0;
