memcpy() is from the C library. And the C library also has memmove(),  
for that matter.

The difference between memcpy() and memmove() is that memcpy() has  
undefined behaviour if the source and destination overlap, while  
memmove() ensures that everything always works fine.

As a result, calling the Pascal version "move" is logical.
