memcpy -- copy byte string
Standard C Library (libc, -lc)
#include <string.h>
void *
memcpy(void *dst, const void *src, size_t len);
The memcpy() function copies len bytes from string src to string dst.
The memcpy() function returns the original value of dst.
bcopy(3), memccpy(3), memmove(3), strcpy(3)
The memcpy() function conforms to ISO/IEC 9899:1990 (``ISO C89'').
In this implementation memcpy() is implemented using bcopy(3), and therefore
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.
