_lrotl()                Rotate a Long Value to the Left

 #include   <stdlib.h>

 unsigned long _lrotl(value,count);
 unsigned long value;
 int        count;

    _lrotl() rotates an unsigned long 'value' to the left by 'count'
    bits.

       Returns:     The rotated value.

   -------------------------------- Example ---------------------------------

    The following statements rotate 'val' by 'count' bits.

           #include <stdlib.h>

           main()
           {
               unsigned long val = 0xFFFF;
               int count = 1;

               printf("rotate %08lX %d bit(s) = %08lX \n",
                       val,count,_lrotl(val,count));
           }
