You should call SLsmg_refresh only when you want the screen to be
updated.  You can achieve what you want in two ways:

1.  
   
   SLsmg_Newline_Behavior = SLSMG_NEWLINE_MOVES;
   while(fgets(string,80,fptr) != NULL)
     SLsmg_write_string(string);
   SLsmg_refresh();
   getchar();

2. (preferred solution)
   
   int row = 0;
   while(fgets(string,80,fptr) != NULL)
     {
	SLsmg_gotoc (row, 0);
	SLsmg_write_string(string);
	row++;
     }
   SLsmg_refresh();
   getchar();

I encourage you to look at slang/demo/pager.c.
