I have been assigned to get the Shareaza source code running and
then to add some functionality to it. The open source is
theoretically what was used to generate a working Shareaza
executable, but I'm finding it kind of hard to believe that this
code was actually compiled. Take this section, for instance:
//! \brief generic function to swap the byte ordering of a given
type //!
//! The byte ordering can be swapped meaningfully only for unsigned
integer types
//! therefore specializations are provided only for those types. We
use
//! template specialization in order to avoid automatic argument
conversion.
template<typename T>
struct SwapEndianess {};
template<> struct SwapEndianess< uint8>
{
uint8 operator()(uint8 value) const { return value; }
};
template<> struct SwapEndianess< uint16>
{
uint16 operator()(uint16 value) const
{
return _byteswap_ushort( value );
}
};
template<> struct SwapEndianess< uint32>
{
uint32 operator()(uint32 value) const
{
return _byteswap_ulong( value );
}
};
template<> struct SwapEndianess< uint64>
{
uint64 operator()(uint64 value) const
{
return _byteswap_uint64( value );
}
};
template<typename T>
inline T swapEndianess(T value)
{
return SwapEndianess< T>()( value ); //<--- Error!
}
I added the little comment pointing at the error. Of this line the
compiler says,
"1>c:<pathname>\shareaza\hashlib\utility.hpp(221): error C2064:
term does not evaluate to a function taking 1 arguments".
