NAME
fmt_ip4 - write a formatted ASCII representation of an IPv4 numberSYNTAX
#include <libowfat/ip4.h>unsigned int fmt_ip4(char *dest,const char ip[4]);
DESCRIPTION
fmt_ip4 formats an IPv4 number in dotted-decimal ASCII representation from ip and writes the result into dest. It returns the number of bytes written.If dest 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.
EXAMPLE
#include <libowfat/ip4.h>char buf[IP4_FMT]; char ip[4]; buf[fmt_ip4(buf,ip)]=0;
