Usage

   #include <stdlib.h>
   unsigned int _rotl(unsigned int val, int shift);

Description

   The functions _rotl and _rotr carry out a binary rotation of the supplied
   unsigned integer, val, by shift bits.

Example 

   #include <stdio.h>
   #include <stdlib.h>

   int main()
   {
       unsigned int value = 0x01234;

       printf("_rotl(value,4) = 0x%4.4x\n",
               _rotl(value,4));
       printf("_rotr(value,8) = 0x%4.4x\n",
               _rotr(value,8));

       return EXIT_SUCCESS;
   }

Return Value

   Both of these functions return the rotated value as an unsigned int.
   There is no error return.
