c++ template function pointer problem

error C2664: 'Lex::LinkedList::setSortQuery' : cannot convert parameter 1 from 'Lex::LinkedList::SortReturnCode (__cdecl *)(const Data,const Data)' to 'Lex::LinkedList::SortReturnCode (__cdecl *)(const T,const T)'
with
[
T=Data *
]
None of the functions with this name in scope match the target type[/quote]

Here is a code snippet



template<class T>
class LinkedList
{
public:

enum SortReturnCode{LOWEST=1, HIGHEST=2, IDENTICAL=4};

typedef SortReturnCode (*SortQueryFncPtr)(const T Data1, const T Data2);

void setSortQuery(SortQueryFncPtr pSortQueryFncPtr)
{
m_pSortQueryFncPtr = pSortQueryFncPtr;
}

private:

SortQueryFncPtr m_pSortQueryFncPtr;
};

struct Data
{
char cTest[255];
};

static LinkedList<Data*>::SortReturnCode SortTest(const Data *Test1, const Data *Test2)
{
return LinkedList<Data*>::IDENTICAL;
}

int main()
{
LinkedList<Data*> listTest;

listTest.setSortQuery(SortTest);

return 0;
}

If I create a list container that contains a non-pointer value, (T=Data), then there is no error. Could anyone be kind to explain why I retrieve this error.

thanks
