.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;
