GDN:memcpy

The memcpy function copies size bytes from the object beginning at from into the object beginning at to. The behavior of this function is undefined if the two arrays to and from overlap; use memmove instead if overlapping is possible.

The value returned by memcpy is the value of to.

Prototype

<source lang="c">void * memcpy (void *restrict to, const void *restrict from, size_t size)</source>

Example

<source lang="c"> struct foo *oldarray, *newarray;

         int arraysize;
         ...
         memcpy (new, old, arraysize * sizeof (struct foo));
