MEMCPY(3)	       FreeBSD Library Functions Manual		     MEMCPY(3)

NAME
     memcpy -- copy byte string

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memcpy(void *dst, const void *src,	size_t len);

DESCRIPTION
     The memcpy() function copies len bytes from string	src to string dst.

RETURN VALUES
     The memcpy() function returns the original	value of dst.

SEE ALSO
     bcopy(3), memccpy(3), memmove(3), strcpy(3)

STANDARDS
     The memcpy() function conforms to ISO/IEC 9899:1990 (``ISO	C90'').

BUGS
     In	this implementation memcpy() is	implemented using bcopy(3), and	there-
     fore the strings may overlap.  On other systems, copying overlapping
     strings may produce surprises.  Programs intended to be portable should
     use memmove(3) when src and dst may overlap.
