#### OS/161 Reference Manual

### Name

memcpy - copy region of memory

### Library

### Synopsis

#include <string.h>
void *
memcpy(void *dest, const void *src, size_t len);

### Description

The block of memory beginning at src, of length len, is copied to dest. dest must point to a region large enough to hold it.

memcpy is not guaranteed to operate correctly if src and dest overlap. Use memmove on overlapping regions.
