Normally I'd say use standard library features

the union of bit fields with an integer of the correct size has some advantages:
- you can name your bits

typedef std::bitset<8> MyBits;

enum e_REG { RX0E, TX0E, RX1E, TX1E, RX2E, TX2E, EOFF, FNEF};
enum e_VAL { val_OK = 0, val_SOMETHING = 0x4A, val_FAILURE = 0x8f, /*etc...*/};

MyBits myReg(val_SOMETHING);
myReg[RX2E] = true;
if (myReg == MyBits(val_FAILURE))

you can deal with collections of bits (electronic engineers like packing them it, so you'll often get things like a 4 bit number, a 2 bit number and 2 x 1 bit numbers in one 8 bit register)

memset(&samples_buffer[fileBytesRead], 0, 8);

// self destruction
void CView::PostNcDestroy()
{
	// default for views is to allocate them on the heap
	//  the default post-cleanup is to 'delete this'.
	//  never explicitly call 'delete' on a view
	delete this;
}

pView->OnClose();

delete pView;
