how to sort CAtlArray using qsort

This is nothing new at all,here is the source code:

CAtlArray< CSomeClass*> m_myArray;
qsort(m_myArray.GetData(), m_myArray.GetCount(), sizeof(CSomeClass*),
  (int(*)(const void*, const void*))SortTheArray);

the Comparison function would look like the following:

int __cdecl SortTheArray(CSomeClass **pp1, CSomeClass **pp2)
{
    ....
}

Wang On February 1st, 2010 at 11:27 pm (#): Good point. But what if CAtlArray contains structs instead of pointers? I am using
struct MyFile { CString sFilename; LARGE_INTEGER Lcn; DWORD dwFragments; };
CAtlArray<MyFile> asFiles;
After sorting, the CStrings are messed up, and once the array is cleaned up there is an access violation.
