realloc prompting incompatible type

nirmalpg124

my code is:

-----> dataStructures.h

typedef struct node
{
        int info;
        struct node *next;
}Node;

------> createLL.c :            // create a Linked List

#include "headers.h"
#include "declerations.h"
#include "dataStructures.h"

Node *start=NULL;
Node *last=NULL;
Node *New=NULL; // for temporary reception of memory
int counter=0;
Node *NEW=NULL; // for reallocation of memory

void* createLL(void* arg)
{

do

{

New = (Node*)(*fptr[3])(arg); // func called for creating a node using malloc

    NEW = (Node*)realloc(NEW, counter*sizeof(Node));

                        if(!NEW)
                        {
                               perror("realloc");
                               (*fptr[1])( (void*)"failure" ); //exitProgram

                        }

                        NEW[counter-1]= New;
                        NEW[counter-1].info = (*last).info;
                        NEW[counter-1].next = (*last).next;

counter++;

printf("Do you want to push another node into the Linked List.?y/n\n");
scanf("%c", &ch);

}while(ch=='y' || ch=='Y')

}

Something like this, irrelevant code omitted.

Error:

createLL.c: In function ‘createLL’:
createLL.c:71:41: error: incompatible types when assigning to type ‘Node’ {aka ‘struct node’} from type ‘Node *’ {aka ‘struct node *’}
71 | NEW[counter-1]= New;
