.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;
|
