Syntax

#include <string.h>  /* also in <memory.h> */
void *memmove(void *dest, const void *src, size_t count);

memmove copies count bytes of src to dest. memmove allows copying between objects that may overlap as if src is first copied into a temporary array.

memmove returns a pointer to dest.

This example copies the word shiny from position target + 2 to position target + 8.

#include <string.h>
#include <stdio.h>

#define  SIZE          21
char target[SIZE] = "a shiny white sphere";

int main(void)
{
   char *p = target+8;                    /* p points at the starting character
                                             of the word we want to replace   */
   char *source = target+2;                               /* start of "shiny" */

   printf("Before memmove, target is \"%s\"\n", target);
   memmove(p, source, 5);
   printf("After memmove, target becomes \"%s\"\n", target);
   return 0;

      The output should be:
