Raw assignment doesn't work!

Code:

---

PIXELFORMATDESCRIPTOR pfd = 0x28000100250000000020000000000000000000000000001000000000000000000000000000000000;

---

I'm sure you see what I'm trying to do. Anyway, the error is

Quote:

---

conversion from `int' to non-scalar type `tagPIXELFORMATDESCRIPTOR' requested

---

Why won't it let me do a raw assignment? And how do I get around that?

Also,

Code:

---

  PIXELFORMATDESCRIPTOR pfd;
  memset(&pfd, 0x28000100250000000020000000000000000000000000001000000000000000000000000000000000, sizeof(PIXELFORMATDESCRIPTOR));

Doesn't work.

What are you trying to do?

My first choice would be struct initialization the normal way.

But if you want to copy a byte array, it is done something like this.

Code:

---

  const unsigned char init[] =
  {
      0x28,0x00,0x01,0x00,0x25,0x00,0x00,0x00,
      0x00,0x20,0x00,0x00,0x00,0x00,0x00,0x00,
      0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x10,
      0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
      0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
  };
  PIXELFORMATDESCRIPTOR pfd;
  memcpy(&pfd, init, sizeof pfd);

You cannot have integer literals larger than the largest type. Also, it wouldn't help you because memset's parameter only takes an int.

What's wrong with just initializing the PIXELFORMATDESCRIPTOR's fields?

Code:

---

PIXELFORMATDESCRIPTOR pfd = { sizeof(PIXELFORMATDESCRIPTOR), 1,
  PFD_DOUBLEBUFFER | PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL,
  PFD_TYPE_RGBA, 32, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 16, 0, 0, 0, 0, 0, 0, 0 };

---

It's a bit more readable than the "raw assignment" (there's no such thing).
Even more readable would be to assign the fields by name.

Yeah, I'm just doing that...

How did you know those where my member contents?

Because that's the order your data is in, perhaps?

Nah, can't be anything that obvious. It must be because I'm psychic ;)
