_rotl()                 Rotate a Value to the Left

 #include <stdlib.h>

 unsigned   _rotl(value,count);
 unsigned   value;
 int        count;

    _rotl() rotates an unsigned '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 val = 0xAA;
              int count = 1;

           printf("rotate %04X %d bit(s) = %04X\n",
                         val,count,_rotl(val,count));
           }
