Defined in header <string.h>
void* memmove( void* dest, const void* src, size_t count );

Copies count characters from the object pointed to by src to the object pointed to by dest. The objects may overlap: copying takes place as if the characters were copied to a temporary character array and then the characters were copied from the array to dest.

Parameters

dest	-	pointer to the memory location to copy to
src	-	pointer to the memory location to copy from
count	-	number of bytes to copy

Return value

dest

Example

Run this code

#include <stdio.h>
#include <string.h>
 
int main(void)
{
    char str[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    puts (str);
    memmove (str+6,str+3,7);
    puts (str);
    return 0;
}

Output:

ABCDEFGHIJKLMNOPQRSTUVWXYZ
ABCDEFDEFGHIJNOPQRSTUVWXYZ
