#include <string.h>

void *memcpy (
  void *dest,          /* destination buffer */
  const void *src,     /* source buffer */
  unsigned int len);   /* bytes to copy */

The memcpy function copies len bytes from src to dest. If these memory buffers overlap, the memcpy function cannot guarantee that bytes in src are copied to dest before being overwritten. If these buffers do overlap, use the memmove function.

Return Value

The memcpy function returns dest.
