Little Endian vs Big Endian

Big Endian = 0x31014950
Little Endian = 0x50490131

However Using this Method

inline unsigned int endian         


        

Answer 1

If I run the code you posted, it gives the correct result: endian_swap ( 0x31014950 ) == 0x50490131.

To get the result: endian_swap ( 0x31014950 ) == 0x54110131, your code must be equivalent to this:

#define __
inline unsigned int endian_swap(unsigned int& x)  
{                  //0x31014950  ->            0x54110131
    return  ( ( (x & 0x000000FF) << 24 ) |   //  50
        __    ( (x & 0x00F0F000) << 12 ) |   //   4
        __    ( (x & 0x00FF0000) << 4  ) |   //    1  
        __    ( (x & 0x00FF0000) << 0  ) |   //     1  
        __    ( (x & 0x00FF0000) >> 8  ) |   //      01
        __    ( (x & 0xFF000000) >> 24 ) );  //        31        
}

Check you haven't got similar differences in your code too.
