Hello,

If you look at a BSD machines man pages you will find out
that the functions missing on the HP are relatively simple
to replace.  You can use the alternative routines below
which have similar functions, or write your own.  Examples
of some of the stuff I have used are below:

................................................................
To use replacemnts  for bcopy, index, and rindex
................................................................

#include <memory.h>
#include <strings.h>
#define bcopy(source,dest,count)	memcpy(dest,source,count)
#define index(string,ch) strchr(string,ch)
#define rindex(string,ch) strrchr(string,ch)

................................................................
Easy code to rewrite though (please check for errors)
................................................................

/*
 * bcmp -- cmp b1 and b2, return 0 if identical, non-zero otherwise
 */
bcmp(b1,b2,length)
char *b1,*b2;
int length;
{
	int i;
	for (i=0;i<length;i++) if (b2[i] != b1[i]) return(1);
	return(0);
}
/*
 * bcopy -- copy "length" bytes from b1 to b2
 */
bcopy(b1,b2,length)
char *b1,*b2;
int length;
{
	int i;
	for (i=0;i<length;i++) b2[i] = b1[i];
}
/*
 * bzero -- copy "length" 0 bytes into b1
 */
bzero(b1,length)
char *b1;
int length;
{
	int i;
	for (i=0;i<length;i++) b1[i] = 0;
}

Have fun porting whatever code your working on...
