Here's the Linux man page on bcopy:
BCOPY(3) LINUX Programmer's Manual BCOPY(3)
NAME
bcopy - copy byte strings
SYNOPSIS
#include <string.h>
void bcopy (const void *src, void *dest, int n);
DESCRIPTION
The bcopy() function copies the first n bytes of the
source string src to the destination string dest. If n is
zero, no bytes are copied.
RETURN VALUE
The bcopy() function returns no value.
CONFORMING TO
BSD 4.3

And Here is the SunOS manpage on bcopy:
BSTRING(3) C LIBRARY FUNCTIONS BSTRING(3)
NAME
bstring, bcopy, bcmp, bzero, ffs - bit and byte string
operations
SYNOPSIS
void
bcopy(b1, b2, length)
char *b1, *b2;
int length;
int bcmp(b1, b2, length)
char *b1, *b2;
int length;
void
bzero(b, length)
char *b;
int length;
int ffs(i)
int i;
DESCRIPTION
The functions bcopy, bcmp, and bzero() operate on variable
length strings of bytes. They do not check for null bytes
as the routines in string(3) do.
bcopy() copies length bytes from string b1 to the string b2.
Overlapping strings are handled correctly.
bcmp() compares byte string b1 against byte string b2,
returning zero if they are identical, non-zero otherwise.
Both strings are assumed to be length bytes long. bcmp() of
length zero bytes always returns zero.
bzero() places length 0 bytes in the string b.
ffs() finds the first bit set in the argument passed it and
returns the index of that bit. Bits are numbered starting
at 1 from the right. A return value of zero indicates that
the value passed is zero.
NOTES
The bcmp() and bcopy() routines take parameters backwards
from strcmp() and strcpy().

bcopy() is considered old and unportable. Use memcpy() instead...
