| Code: |
__checkReturn BOOL CalculateCrc(__in_deref PBYTE pData, __in SIZE_T dwLength, __out PDWORD pChecksum)
{
BOOL bRet = TRUE;
DWORD dwChecksum = 0;
unsigned int i;
for (i = 0; i < dwLength; i++)
{
try
{
dwChecksum += (pData[i] * i);
}
except (EXCEPTION_EXECUTE_HANDLER)
{
bRet = FALSE;
}
}
return bRet;

Will it crash if I check 1000+ bytes?

What happens to pChecksum?
Also, why not UINT?
