Code:
typedef struct node {
   int list_data;
   struct node *next;
} NODE;

void Linear2Circular (NODE *list) {
   
   NODE *tmp = list;
   if(NULL != tmp) {
      /*
      ** The list has one or more nodes.
      */
      while (NULL != tmp->next)
         tmp = tmp->next;

      tmp->next = list;   //Converted into the circular formation.
   }
}
