IsValidPE

Why this not is functional? ...

Code:

---

int isValidPE(LPVOID pMapping)
{
        PIMAGE_DOS_HEADER DosHeader = (PIMAGE_DOS_HEADER) pMapping;

        if (DosHeader->e_magic == IMAGE_DOS_SIGNATURE)
        {
                PIMAGE_NT_HEADERS NtHeaders = (PIMAGE_NT_HEADERS) ((char*) DosHeader + DosHeader->e_lfanew);

                if (NtHeaders->Signature == IMAGE_NT_SIGNATURE)
                        return 1;
                else
                        return 0;
        }
        else
                return 0;
}
