.TH fmt_ip6c 3
|
||
|
|
.SH NAME
|
||
|
|
fmt_ip6c \- write a formatted ASCII representation of an IPv6 number
|
||
|
|
.SH SYNTAX
|
||
|
|
.B #include <ip6.h>
|
||
|
|
|
||
|
|
unsigned int \fBfmt_ip6c\fP(char *\fIdest\fR,const char \fIip\fR[16]);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
fmt_ip6c 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_ip6c will apply "::" compression to the output.
|
||
|
|
|
||
|
|
If \fIip\fR is an IPv4-mapped IPv6 address, fmt_ip6c will output it as
|
||
|
|
IPv4 address.
|
||
|
|
|
||
|
|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ip6c returns the number
|
||
|
|
of bytes it would have written.
|
||
|
|
|
||
|
|
fmt_ip6c does not append \\0.
|
||
|
|
|
||
|
|
For convenience, ip6.h defines the integer IP6_FMT to be big enough to
|
||
|
|
contain every possible fmt_ip6c output plus \\0.
|
||
|
|
.SH EXAMPLE
|
||
|
|
#include <ip6.h>
|
||
|
|
|
||
|
|
char buf[IP6_FMT];
|
||
|
|
char ip[16];
|
||
|
|
buf[fmt_ip6c(buf,ip)]=0;
