please verify the code

Hello, All!

I wrote function parsing the fully-quilified domain name and extracting
'host' and 'domain' parts seperately. The important thing for me is to keep
original string (pointed by 'fqdn' in function). Is my way of coding
correct, is there a way to optimize function and make it not so clumsy (I
like the code produced by K&R in their famous book: brief, clear,
comprehensible, nothing superfluous :) ).

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define BUFLEN 1024

static int
parse_fqdn(char *fqdn, char *host, char *domain)
{
char p[BUFLEN], *s;

strcpy(p, fqdn);
if ( (s = strstr(p, ".")) ) {
*s = '\0';
strcpy(host, p);
strcpy(domain, ++s);
return 0;
}
else
return -1;
}

int main(void)
{
char dom[] = "www.my.example.dom.ain";
char h[BUFLEN], d[BUFLEN];

if ( parse_fqdn(dom, h, d) == 0 )
printf("fqdn='%s'\nhostname='%s', domain name='%s'\n", dom, h, d);
return 0;
}

Thanks in advance
