MEMCPY(3) BSD Library Functions Manual MEMCPY(3)NAMEmemcpy — 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 ALSObcopy(3), memccpy(3), memmove(3), strcpy(3), wmemcpy(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.
