NAME
memcpy -- copy byte string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h> void * memcpy(void * restrict dst, const void * restrict src, size_t len); void * mempcpy(void * restrict dst, const void * restrict src, size_t len);
DESCRIPTION
The memcpy() and mempcpy() functions copy len bytes from string src to string dst. The arguments must not overlap -- behavior if the arguments overlap is undefined. To copy byte strings that overlap, use memmove(3).
RETURN VALUES
The memcpy() function returns the original value of dst. The mempcpy() function returns a pointer to the byte after the last writ- ten byte.
SEE ALSO
