Thread: 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;
}
