hmemmove

#include <string.h>

void huge *hmemmove (
  void huge *dest,        /* destination buffer */
  const void huge *src,   /* source buffer */
  unsigned long len);     /* bytes to move */

The hmemmove function copies len bytes from src to dest. If these memory buffers overlap, the hmemmove function ensures that bytes in src are copied to dest before being overwritten.

Note

• This function uses huge pointers to objects.

The hmemmove function returns dest.
