Hi ,I have trable with deletiing all records in linked list

Code:

{
   while(*head!=NULL)
  {
    * head=(*head)->next;
   }
   free(*head);

You need to utilize a temporary pointer to point to next element before freeing it:

Code:

record *rnext;
while(*head)
{
  rnext = (*head)->next;
  free(*head);
  *head = rnext;
}

Code:

void nom( struct node *n )
{
    if( n )
    {
        nom( n->next );
        free( n );
    }
}

Sometimes recursion really is more elegant.
