一個好用的hash函數（C語言）

 typedef unsigned  typedef unsigned  
          
 inline DWORD mk_hash_index(DWORD*       BYTE*     DWORD*      DWORD dwHashVal =   
     dwKeyLen =     pKey = (DWORD* 
     (dwi = dwKeyLen/(DWORD); dwi>; dwi--          dwHashVal = ((dwHashVal << ) + dwHashVal) + *         pKey++      dwi = (DWORD) - (dwKeyLen%     pKeyEnd = (BYTE*)pKey+     (dwi-- >           *pKeyEnd-- =       dwHashVal = ((dwHashVal << ) + dwHashVal) + *     dwHashVal = dwHashVal %      }
